Two new complexes, [Cu(abpt) 2 (dca) 2 ] and [Co(abpt) 2 (dca) 2 ] (abpt = 4-amino-3,5-bis-(pyridin-2-yl)-1,2,4-triazole; dca = dicyanamide), have been prepared and magneto-structurally characterised.
Complexes [Co(biq)(μ1,5-dca)2]n (1) and [Ni(biq)(μ1,5-dca)2]n (2) (biq is 2,2΄-biquinoline, dca is dicyanamide anion, N(CN)2–) have been characterized by crystal structure analysis, and spectral and magnetic measurements. The crystal structures of...
From Co(NO3)2·6H2O ‐ NaN3 ‐ abpt reaction system, a mononuclear complex [Co(abpt)2(N3)2] (abpt = 4‐amino‐3,5‐bis(pyridin‐2‐yl)‐1,2,4‐triazole) (1) and a dinuclear complex [Co2(abpt)(µ‐abpt‐H)2(N3)4]·1.12H2O (2) were obtained. The presence of neutral abpt, as well as azido ligands was proved by IR spectroscopy. X‐ray crystallography shows that 1 is...
From the system CuCl2–biq–NaN(CN)2 (biq is 2,2′-biquinoline), the binuclear molecular complex bis(μ-dicyanamido-κ²N¹:N⁵)bis[(2,2′-biquinoline-κ²N,N′)(dicyanamido-κN¹)copper(II)], [Cu2(C2N3)4(C18H12N2)2] or [Cu2(biq)2(dca)2(μ1,5-dca)2] (1) [dca is dicyanamide, N(CN)2⁻] was isolated and characterized by crystal structure analysis, and spectral,...
From the system CuCl 2 – pbi – NaN(CN) 2⁻ , polymeric [CuCl(μ 1,5 -dca)(pbi)] n ·nH 2 O ( 1 ) complex (dca=dicyanamide, pbi=2-(2-pyridyl)benzimidazole) was isolated and characterized by structure analysis, spectral and magnetic measurements. Infrared spectroscopy confirmed the presence of pbi, dca and water molecules in 1 . Its solid-state structur...
The complex (2,2′-biquinoline-κ²N,N′)(carbamoylcyanonitrosomethanide-κ²N,O)chloridocopper(II) acetonitrile monosolvate, [Cu(C3H2N3O2)Cl(C18H12N2)]·CH3CN or [Cu(ccnm)Cl(biq)]·acn (acn is acetonitrile, biq is 2,2′-biquinoline and ccnm is carbamoylcyanonitrosomethanide), (I), was prepared as a result of nucleophilic addition of water to the...
A series of mononuclear hexacoordinate Co(II) complexes with 4-amino-3,5-bis(2-pyridyl)-1,2,4-triazole (abpt) ligand and various linear and non-linear pseudohalides, such as NCSe (selenocyanate), N{C(CN)2}2 (1,1,3,3-tetracyano-2-azapropenide, tcap), NO2C(CN)2 (nitrodicyanomethanide, nodcm), C(CN){C(CN)2}2 (1,1,2,3,3-pentacyanopropenide, pcp), NO2NC...
Ionic cobalt(II) complex [Co(dcnm)(H2O)(phen)2](dcnm) (1) (dcnm = dicyanonitrosomethanide, phen = 1,10-phenantroline) has been prepared by a diffusion technique. Its structure is formed by [Co(dcnm)(H2O)(phen)2]⁺ complex cation and free dcnm counterion in the lattice which acts as a hydrogen-bond acceptor to the hydrogen bonds from the water ligand...
Two new complexes, [CoII(_bpy_)2(dca)2] (1) and [CoII(_bpy_)2(tcm)2] (2) (_bpy_ = 2,2-bipyridine, dca = dicyanamide and tcm = tricyanomethanide) were prepared as powders. During their recrystallization on air, two other new complexes, [CoIII(_bpy_)2CO3]dcg (dcg = N,N’-dicyanoguanidine, (H2N)C(NCN)2) (3) and [CoIII(_bpy_)2CO3]tcm·2H2O (4), have been...
Five Co(II)-L-X complexes, where L = 1,10-phenanthroline (phen) or 2,2′-bipyridine (bpy) and X = dicyanamide (N(CN)2−) or tricyanomethanide (C(CN)3−) anions, have been synthesized and characterized by single crystal X-ray diffraction studies. The dca and tcm anions exhibit monodentate or μ1,5-bidentate bridging modes. In two complexes, tcm acts as...
Mixed-ligand Cu(II) and Ni(II) complexes, [Cu(dmit)(bpy)]2 (I), [Ni(dmit)(phen)2] (II) and [Ni(dmit)(phen)2]·CH2Cl2 (III) (dmit=1.3-dithiole-2-thione-4.5-dithiolate, phen=1.10-phenantroline, bpy=2.2′-bipyridine) have been prepared by ligand exchange between phen or bpy and (Bu4N)2[M(dmit)2] (M=Ni, Cu) and characterized by elemental analysis, IR spe...
The splitting of the quasidegenerate electronic states in dinuclear bis[(1,3-dithiole-2-thione-4,5-dithiolato)-di-(carbonyl) -cyclopentadienyliron (II)] complex with the bridging, S–S coupled, dimerized sulfur-rich dithiolate ligands, [Fe(C5H5)(CO)2(C3S5-C3S5)Fe(C5H5)(CO)2] (I) was found by the means of
Mössbauer spectroscopy and by the measurement...
The synthesis of a mixed-ligand complex 1,3-dithiole-2-thione-4,5-dithiolato-bis(1, 10-phenanthroline)zinc(II), [Zn(Dmit)(Phen)(2)], is described.

The coordination polyhedron of the Zn(II) atom is...
The formation and growth of lead sulfide nanocrystals in lead stearate Langmuir–Blodgett (LB) films are investigated by optical absorption spectroscopy. Kinetics of the concentration changes of lead ions in the different states formed during the growth process, as well as the evolution of the nanocrystal average size versus growth time, are studied...
