Trans-Diaquabis(5-methylpyrazine-2-carboxylato-κ2O,N)zinc(II)

Abstract

The crystal structure of the title compound, [Zn(C6H5N2O2)2(H2O)2], consists of discrete mononuclear complex mol­ecules. The ZnII ion is located on an inversion centre and is coordinated in a trans mode by the N,O-bonding groups donated by two 3-methyl­pyrazine-2-carboxyl­ate ligands [Zn—N = 2.109 (1) Å and Zn—O = 2.090 (1) Å] and by two aqua O atoms [Zn—O = 2.129 (2) Å]. The coordination geometry around the ZnII ion is slightly distorted octa­hedral. The crystal structure is stabilized by a network of O—H⋯O hydrogen bonds operating between the coordinated water mol­ecules and carboxyl­ate O atoms.
