In the title compound, [Cd(C2N3)2(C10H8N2)2], the CdII ion is coordinated in a distorted octahedral environment by four N atoms from two chelating 2,2′-bipyridine ligands and two N atoms from two monodentate dicyanamide ligands. The dihedral angle between the mean planes of the two bipyridine ligands is 87.67 (6)°.

In the title complex, [Zn(C10H6N3O2)2(H2O)4], the ZnII ion lies on an inversion center and is coordinated in a slightly distorted octahedral geometry by two N atoms from two 2-(pyridin-4-yl)pyrimidine-5-carboxylate ligands and four water molecules. In the symmetry-unique part of the molecule, the pyridine and pyrimidine rings form a dihedral angle of 7.0 (1)°. In the crystal, the coordinating water molecules act as donor groups and carboxylate O atoms act as acceptors in O—H
O hydrogen bonds, forming a three-dimensional network.
