The title complex [Ni(C4H4O5)(C6H6N4S2)(H2O)](2.5H2O has been prepared and its crystal structure was determined by X-ray diffraction method. The crystal belongs to monoclinic, space group P21/n with a = 16.499(2), b = 10.132(1), c = 11.177(2)(A), ( = 109.76(1)o, V = 1758.4(4)(A)3, Mr = 452.11, Z = 4, Dc = 1.708 g/cm3, ( = 1.391 mm-1, F(000) = 932, R = 0.0424 and wR = 0.1088 for 2341 observed reflec- tions (I>2((I)). The complex assumes a distorted octahedral coordination geometry formed by one oxydiacetate dianion, one diaminobithiazole and one coordinated water molecule. The parallel thiazole rings of adjacent complex molecules overlap to each other, and the separation of 3.458(7)(A) suggests the existence of π-π stacking.
