Oxidation of Cs 4 [U(NCS) 8 ] in MeCN or DMF affords structurally characterised examples of the mixed-valent UIV/VI compound Cs 14 [{U(NCS) 8 } 3 {UO 2 (NCS) 4 (H 2 O)]·4.5H 2 O, or the [UIV-UV-UIV][UVI] species [U(DMF) 8 (μ-O)U(NCS) 5 (μ-O)U(DMF) 7 (NCS)][UO 2 (NCS) 5 ]. Vibrational and magnetism data support their oxidation state...

A series of uranyl thiocyanate and selenocyanate of the type [R4N]3[UO2(NCS)5] (R4=nBu4, Me3Bz, Et3Bz), [Ph4P][UO2(NCS)3(NO3)] and [R4N]3[UO2(NCSe)5] (R4= Me4,nPr4, Et3Bz) have been prepared and structurally characterized. The resulting noncovalent interactions have been examined and compared to other examples in the literature. The nature of these...

A series of complexes [Et4N][Ln(NCS)4(H2O)4] (Ln = Pr, Tb, Dy, Ho, Yb) have been structurally characterized, all showing the same structure, namely a distorted square antiprismatic coordination geometry, and the Ln-O and Ln-N bond lengths following the expected lanthanide contraction. When the counterion is Cs(+), a different structural motif is ob...

A series of 10-((4-halo-2,6-diisopropylphenyl)imino)phenanthren-9-ones and derivatives of the phenanthrene-9,10-dione ligand have been synthesised and structurally characterised to explore two types of non-covalent interactions, namely the influence of the steric bulk upon the resulting C—H...pi and pi-stacking interactions and halogen bonding. Sel...

The solid state structure of 1,1,1,2,2,3,3-heptachloropropane is reported. This molecule features numerous type I and type II Cl⋯Cl interactions in the solid state as well as Cl⋯H hydrogen bonds. A Hirshfeld surface analysis is also presented.

The crystal structure of [Ph4P][NCS]·HNCS is reported. This is the first structural determination of isothiocyanic acid and hydrogen bonding between the NCS anion and HNCS fragment explored using computational chemistry.

The first example of a uranyl selenocyanate compound is reported. The compound [Et4N]3[UO2(NCSe)5] has been synthesized and fully characterized by vibrational and multinuclear (¹H, ¹³C{¹H} and ⁷⁷Se{¹H}) NMR spectroscopy. The photophysical properties have also been recorded and trends in a series of uranyl pseudohalides discussed. Spectroscopic evid...
