Abstract
Four transition metal complexes [Zn(topca)2(H2O)2], [Zn(topca)2(H2O)2]·2H2O, [Ni(topca)2(H2O)2]·2H2O and [Cd(topca)2 (H2O)2], (Htocpa = 1,4,5,6-tetrahydro-6-oxo-3- pyridazinecarboxylic acid), have been synthesised and their X-ray structures determined. The complexes are isomorphous, and the metal centres are six-coordinated with two pyridazinyl N atoms, two carboxyl O atoms from two ligands and two water molecules.
