ABSTRACT
The reaction of 2,5-bis-(pyridin-4-yl)-1,3,4-oxa-diazole (4-pox) and thio-cyanate ions, used as co-ligand with nickel salt NiCl2·6H2O, produced the title complex, [Ni(NCS)2(C12H8N4O)2(H2O)2]. The NiII atom is located on an inversion centre and is octa-hedrally coordinated by four N atoms from two ligands and two pseudohalide ions, forming the equatorial plane. The axial positions are occupied by two O atoms of coordinated water mol-ecules. In the crystal, the mol-ecules are linked into a three-dimensional network through strong O-Hâ¯N hydrogen bonds. Hirshfeld surface analysis was used to investigate the inter-molecular inter-actions in the crystal packing.
