✦ Synopsis

In the title complex, [Ni(C 5 H 3 N 6 ) 2 (H 2 O) 2 ], the Ni II atom is located in a general position and is coordinated by four N atoms from two 5-(pyrimidin-2-yl)tetrazolate ligands and O atoms of two water molecules in a distorted octahedral geometry. The bond distances and angles around the metal center lie in the ranges 2.051 (5)-2.097 (5) A ˚and 78.88 (19)-101.22 (19) , respectively. The title complex is isostructural with its Mn II and Cu II analogues; it is, however, structurally different from an Ni II complex obtained by direct reaction of 2-(1H-tetrazol-5-yl)pyrimidine with an Ni II salt under hydrothermal conditions. In the crystal structure, molecules are linked together by O-HÁ Á ÁN hydrogen bonds, forming a twodimensional network parallel to the (001) plane.
