2N1,N5]cadmium(II) dihydrateAbstract: In the title complex, [Cd(C7H4N5O2)2(H2O)2]·2H2O, the water-coordinated CdII atom (
symmetry) is coordinated by four N atoms from two symmetry-related 3-carboxypyidyl-6-tetrazolato ligands, forming a distorted octahedral complex. The uncoordinated water molecules connect the mononuclear units into a layer structure through O-H
N and O-HO hydrogen bonds; similar hydrogen bonds between coordinated water molecules and anionic groups result in a three-dimensional structure.
