In the monomeric title complex, [Cd(C2O4)(CH3N5)2(H2O)2], the CdII ion exhibits a distorted octahedral coordination geometry, with the equatorial plane defined by two O atoms from an oxalate ligand and two N atoms from two 5-amino-1H-tetrazole ligands; the axial sites are occupied by two water molecules, with longer Cd—O bond lengths. An intramolecular N—HO hydrogen bond occurs. In the crystal, N—HO as well as O—HO and O—HN hydrogen bonds (some of which are bifurcated) link the complex molecules into a three-dimensional network.
