Abstract: 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-H...O hydrogen bond occurs. In the crystal, N-H...O as well as O-H...O and O-H...N hydrogen bonds (some of which are bifurcated) link the complex mol­ecules into a three-dimensional network.
