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

In the crystal structure of the title complex, [Cd(NCS)(2)(C(7)H(5)ClN(4))(2)](n), the Cd(II) atom lies on a crystallographic inversion center and assumes a distorted octa-hedral geometry. The 2-chloro-6-(1H-1,2,4-triazol-1-yl)pyridine mol-ecule acts as a terminal ligand. The thio-cyanate ligands function as μ(1,3)-bridging units connecting adjacent Cd(II) atoms with a separation of 5.7525 (11)...

In the title crystal structure, [Cd(NCS)(NO(3))(C(11)H(9)N(5))](n), the unique Cd(II) ion is coordinated in a distorted penta-gonal-bipyramidal environment. The axial thio-cyanate ligands act in a μ(1,3)-bridging mode to connect symmetry-related Cd(II) ions into one-dimensional chains along [010]. In addition, there are inter-molecular C-H⋯O contacts between chains.
