Diaquabis(5-methylpyrazine-2-carboxylato-κ²N¹,O²)cadmium

Abstract

In the title compound, [Cd(C6H5N2O2)2(H2O)2], the CdII ion is coordinated in a severely distorted octa­hedral geometry. The N atoms are cis to each other, while the water O atoms and ligand O atoms are mutually trans. The crystal structure is stabilized by a network of O—H⋯O, O—H⋯N and C—H⋯O hydrogen bonds and π–π stacking inter­actions [centroid–centroid distances = 3.730 (3) and 3.652 (3) Å] between the 5-methyl­pyrazine-2-carboxyl­ate ligands. The structure is isotypic with the manganese analog.
