【 摘 要 】

Reaction of Co(NCS)2 and Zn(NCS)2 with 4-pyridine­thio­amide led to the formation of compounds with composition [Co(NCS)2(C6H6N2S)4]·H2O (1) and [Zn(NCS)2(C6H6N2S)2] (2), respectively. The asymmetric unit of compound 1, consists of one cobalt(II) cation, two thio­cyanate anions, four 4-pyridine­thio­amide ligands and one water mol­ecule whereas that of compound 2 comprises one zinc(II) cation that is located on a twofold rotation axis as well as one thio­cyanate anion and one 4-pyridine­thio­amide ligand in general positions. In the structure of compound 1, the cobalt(II) cations are octa­hedrally coordinated by two terminal N-bonding thio­cyanate anions and by the N atoms of four 4-pyridine­thio­amide ligands, resulting in discrete and slightly distorted octa­hedral complexes. These complexes are linked into a three-dimensional network via inter­molecular N—H⋯S hydrogen bonding between the amino H atoms and the thio­cyanate S atoms. From this arrangement, channels are formed in which the water mol­ecules are embedded and linked to the host structure by inter­molecular O—H⋯S and N—H⋯O hydrogen bonding. In the structure of compound 2, the zinc(II) cations are tetra­hedrally coordinated by two N-bonding thio­cyanate anions and the N atoms of two 4-pyridine­thio­amide ligands into discrete complexes. These complexes are likewise connected into a three-dimensional network by inter­molecular N—H⋯S hydrogen bonding between the amino H atoms and the thio­amide S atoms.
