2O,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.
