In the centrosymmetic title complex, [Co(C18H12N5)2(H2O)2], the CoII ion is coordinated by two N,N′-bidentate 5-(pyridin-2-yl)-3-[4-(pyridin-4-yl)phenyl]-1H-1,2,4-triazol-1-ide ligands and two water molecules in a trans-CoO2N4 coordination geometry. In the ligand, the dihedral angles between the triazole ring and its adjacent pyridine and benzene rings are 5.57 (14) and 6.89 (16)°, respectively. In the crystal, molecules are linked by O—HN hydrogen bonds, generating a three-dimensional network.

In the centrosymmetric title complex, [Fe(C18H12N5)2(H2O)2], the FeII ion, lying on an inversion centre, is coordinated by two N,N′-bidentate 5-(pyridin-2-yl)-3-[4-(pyridin-4-yl)phenyl]-1H-1,2,4-triazol-1-ide ligands and two water molecules in a trans-FeO2N4 geometry. In the ligand, the triazole ring makes dihedral angles of 5.21 (18) and 6.7 (2)°, respectively, with the adjacent pyridine and benzene rings. In the crystal, molecules are linked by O—HN hydrogen bonds, generating a three-dimensional network.

The asymmetric unit of the title compound, [Zn(C18H12N5)2(H2O)2], consists a ZnII ion, located on an inversion center, a deprotonated 5-pyridin-2-yl-3-[4-(pyridin-4-yl)phenyl]-1H-1,2,4-triazol-1-ido ligand and a water molecule. The whole molecule is generated by inversion symmetry. The ZnII ion has a distorted octahedral coordination geometry, defined by four N atoms from the two deprotonated organic ligands and two water O atoms. In the crystal, O—HN hydrogen bonds link the molecules, forming a three-dimensional network.
