Crystal structure of bis(pyridine-4-carbothioamide-κN¹)bis(thiocyanato-κN)cobalt(II) methanol monosolvate

Abstract

The asymmetric unit of the title compound, [Co(NCS) 2 (C 6 H 6 NS) 4 ]ÁCH 3 OH, consists of one cobalt(II) cation, two thiocyanate anions, four pyridine-4-carbothioamide ligands and one methanol molecule that are located in general positions. The Co II cations are coordinated by two terminal N-bonding thiocyanate anions and four N-bonding pyridine-4-carbothioamide ligands, resulting in discrete and slightly distorted octahedral complexes. These complexes are linked into a three-dimensional network via intermolecular N-HÁ Á ÁS hydrogen bonding between the amino H atoms and the thiocyanate and pyridine-4-carbothioamide S atoms. From this arrangement, channels are formed in which the methanol solvate molecules are embedded and linked to the host structure by intermolecular O-HÁ Á ÁS and N-HÁ Á ÁO hydrogen bonding.

Crystal structures of tetrakis(pyridine-4-thioamide-κN)bis(thiocyanato-κN)cobalt(II) monohydrate and bis(pyridine-4-thioamide-κN)bis(thiocyanato-κN)zinc(II)

“…There is only one cobalt thiocyanate compound with 4-pyridinethioamide reported in the Cambridge Structure Database (Version 5.39; Groom et al, 2016). In tetrakis(pyridine-4-carbothioamide-N 1 )bis-(thiocyanato-N)cobalt(II) methanol monosolvate, the Co II cations are octahedrally coordinated by four pyridine-4-carbothioamide ligands and two thiocyanate anions, and the solvent molecules are located in the cavities of the structure (Neumann et al, 2017).
