Diaqua­bis{2-[5-(2-pyrid­yl)-2 H-tetra­zol-2-yl]acetato-κ ² N ⁴, N ⁵}zinc(II)

Abstract

The title compound, [Zn(C ₈H ₆N ₅O ₂) ₂(H ₂O) ₂], was synthesized by hydro­thermal reaction of ZnBr ₂ with 2-[5-(2-pyrid­yl)-2 H-tetra­zol-2-yl]acetic acid. The Zn ^II atom lies on an inversion center in a distorted octa­hedral environment with two planar trans-related N, N′-chelating 2-[5-(2-pyrid­yl)-2 H-tetra­zol-2-yl]acetic acid ligands in the equatorial plane and two water mol­ecules in the axial positions. In the crystal, O—H⋯O hydrogen bonds generate an infinite three-dimensional network.
