Abstract

In the title compound, [Cd(C 6H 5N 2O 2) 2(H 2O) 2], the Cd II ion is coordinated in a severely distorted octa-hedral 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 ?-? 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.
