    ABSTRACT: New coordination compounds based on 1,3,5-benzenetricarboxylate (btc3−) and complex cations of copper(II) and nickel(II) with monodentate ligands {{[Cu(py)3]3(btc)2}·4,5H2O} n (1) and {[Ni(py)3(H2O)]3(btc)2} n (2) were obtained. The molecular and crystal structures of these compounds and their isomorphism were determined by X-ray diffraction analysis. Crystals of 1 and 2 are characterized by a layered structure due to the stacking of two-dimensional coordination-polymer layers interacting with each other through C-H…π non-covalent interactions and C-H…O weak hydrogen bonds. It is shown that these compounds are potentially highly porous materials with coordinatively unsaturated metal ions (Lewis acid sites).

    ABSTRACT: This review describes the current state of studies on the phenomenon of interpenetration of framework groups in crystal structures. The generally accepted terminology used in the description of topology of interpenetrating motifs, symmetric and topological properties of interpenetrating systems is given. The main advances of crystal chemistry in the systematization of interpenetrating structures are elucidated. It is noted that the major trend in the crystal chemistry of interpenetration is the development of methods for the topological classification of the entanglements of interpenetrating groups and the search for the regularities of their implementation in crystalline substances. The main ways of the formation of interpenetrating structures, the appearing here geometrical-topological restrictions, and also the effect of stereochemical factors and synthesis conditions on the possibility of interpenetration are considered.

    ABSTRACT: The structure of supramolecular complexes of poly-γ-benzyl-L-glutamate (PBG) with water and dioxane molecules during sorption from pure liquids and their binary mixtures is studied by IR spectroscopy and quantum chemical calculations. It is shown that the sorption sites of water and dioxane in PBG are different in nature. Water molecules are bound in the monomeric form to the carbonyl groups of the ester moieties of the side chains and the helical backbone of the peptide to form complexes with two hydrogen bonds. Dioxane molecules are sorbed in a large amount in the region of the side chains of PBG, causing their repacking with preservation of the helicity of the polypeptide backbone. Under simultaneous sorption of water and dioxane vapors, the binding of the latter increases the number of water molecules bound to the carbonyl groups of PBG. In this case, there is also an additional absorption of water molecules on the oxygen atoms of dioxane molecules. Calculations have shown that in the most probable configuration of the complexes, the water molecule simultaneously forms hydrogen bonds with the carbonyl groups of the side chain and the peptide backbone. Dioxane molecules do not penetrate to the peptide groups of helical backbone of PBG due to steric hindrance and are localized in the region of the benzyl moieties of the side chains; such complexes are stabilized by weak CH…O interactions.

    ABSTRACT: The structure and properties of supramolecular complexes of α-chymotrypsin with hydroxyl-containing alkyl ammonium gemini surfactants (GSs) — α,ω-alkanedyl-bis(hydroxyethylmethylcetyl ammonium dibromides), with a polymethylene spacer of varying length have been studied. IR spectroscopy and tryptophan fluorescence data show that the interaction of GSs with α-chymotrypsin leads to changes of different intensity in the structural state of proteins. The most probable complexation mode of enzyme with GSs have been proposed by the molecular docking method. A correlation is found between the activity of α-chymotrypsin and the length of the GS spacer moiety. The enzyme activity correlates with the change in the substrate concentration in the aqueous phase of the surfactant micellar solution.

    ABSTRACT: The aggregation properties of supramolecular systems based on polyethyleneimines and cationic surfactants with a bicyclic head group — mono- and diquaternized derivatives of 1,4-diazabicyclo[2.2.2]octane are studied by surface tension measurements, potentiometry, conductivity measurement, and dynamic light scattering. The critical aggregation concentrations of individual and mixed systems based on them, as well as the size of the ensembles they form are determined. The relationship between the aggregation behavior and hydrophobicity of the polymer and the structure of the cationic surfactant is established.

    ABSTRACT: In connection with the 100th anniversary of the discovery of the phenomenon of the diffraction of X-rays by crystals (Max von Laue, 1912) and the basics of X-ray crystallographic analysis (Lawrence Bragg, 1913), the article marks the major milestones in this outstanding event in the history of science. Special emphasis is given to the role of Russian scientists (E. S. Fedorov, G. V. Vulf) in the emergence and early steps in the establishment of this discovery being one of the pillars of the scientific revolution of the first half of the past century.

    ABSTRACT: X-ray diffraction characteristics are obtained for odd monocarboxylic acids (fatty acids) C n H2n O2 with n = 11, 13, 15, 17, 19, and 21. It is found that all original samples (reagents) of these acids are two-phase. There are found the following modifications: for the acid with n = 11 triclinic Tc (space group P-1) and monoclinic M 3 (space group P21/c); for n = 13 triclinic Tc (space group P-1) and bilayered monoclinic 2M (space group A2/a); for n = 15, 17, 19, 21 two monoclinic M 1 (space group P21/a) and M 3 (space group P21/c). It is demonstrated that the homological series and individual homologues of fatty acids manifest noticeable crystal chemical features such as morphotropism and polymorphism, respectively. Thermal phase transformations of odd fatty acids are studied using pentadecanoic acid C15H30O2 as a representative example. It is found that near the melting point (52 °C) within the temperature range of 45-50 °C the monoclinic phase M 1 of this acid undergoes a polymorphic transformation in the high-temperature bilayered monoclinic phase 2M. The data obtained are compared to those reported in the literature. An express standardless test is developed for the determination of homologues (the n value) and polymorphic modifications of monocarboxylic acids.

    ABSTRACT: The analysis of the literature data reveals that, as a rule, layered double hydroxides prepared by co-precipitation have an imperfect structure; however, there are different viewpoints on the type of the defects. Thermal decomposition of Mg-Al, Mg-Ga, and Ni-Al hydroxides occurs through dehydration, dehydroxylation, and decarbonization. The first stage affords a layered dehydrated phase with a strongly disordered structure, which is a subject of controversy. Also, the question on the diffusion of cations during thermolysis is still open, i.e., whether the Mg-Al, Mg-Ga and Ni-Al systems degrade with the development of a nanoheterogenous oxide systems or a single-phase mixed oxide, but with very defective structure, is formed.

    ABSTRACT: The crystal structures of 12-hydroxynorfluorocurarine (vincanidine) isolated from the plant Vinca erecta, its hydrochloride monohydrate, quaternary salts — chloromethylate and iodomethylate, and the quaternary base (zwitterionic betaine) have been studied. The asymmetric centers of the molecules have the 3S, 7R, 15S configuration. In all cases, the carbonyl group is in a twisted orientation with respect to the N1H group and participates in the intramolecular H-bond with this group. In crystals, the 12-hydroxy group is involved in intermolecular interactions. The quaternary base of 12-hydroxynorfluorocurarine contains a zwitterionic form of the alkaloid due to deprotonation of the 12-hydroxyl group. The packing in the crystal structure of 12-hydroxynorfluorocurarine and the quaternary base contains voids (19.8 % and 21.8 % of the total volume of the crystal cell, respectively) of the channel type along the c crystallographic axis.
