【 摘 要 】

The crystal structure of the title compound, [Cd(NCS)2(C6H7NO)2]n is made up of Cd2+ cations that are coordinated by three thio­cyanate ligands and three 4-(hy­droxy­meth­yl)pyridine ligands within distorted N4OS octa­hedra. The asymmetric unit consists of one Cd2+ cation, two thio­cyanate anions and two 4-(hy­droxy­meth­yl)pyridine ligands in general positions. Two Cd2+ cations are linked by two μ-1,3 N- and S-bonding thio­ycanate anions into dimers which are further linked into branched chains along [100] by two μ-1,6 N- and O-bonding 4-(hy­droxy­meth­yl)pyridine ligands. One additional N-bonded 4-(hy­droxy­meth­yl)pyridine ligand and one additional N-bonded thio­cyanate anion are only terminally bonded to the metal cation. Inter­chain O—H⋯S hydrogen bonds between the hy­droxy H atoms and one of the thio­cyanate S atoms connect the chains into a three-dimensional network.
