Abstract
The structure of the title compound (Ni(CN)2(CH5N3S)·H2O) has been determined, from X-ray diffractometer data, by the heavy-atom method and refined by least-squares. The finalR-values, based on 3109 observed reflections, areR=0.035 andR w =0.039. The complex has square-planar geometry with two adjacent cyano carbon atoms (Ni-C, 1.838(2) Å and 1.862(2) Å)and thiosemicarbazide sulfur and nitrogen atoms (Ni-S, 2.169(1) Å and Ni-N, 1.923(2) Å). The water molecule does not enter the inner coordination sphere of the nickel atom; however, it plays a very important role in the crystal structure. Water is coordinated by hydrogen bonds to four adjacent complex units.
