Diaquabis[5-(pyrimidin-2-yl-N)tetrazolato-N¹]nickel(II)

Y.-E. Qiu

Abstract: In the title complex, [Ni(C₅H₃N₆)₂(H₂O)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) Å 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-HN hydrogen bonds, forming a two-dimensional network parallel to the (001) plane.
