Summary Transition metal complexes of cobalt(II), nickel(II), copper(II) and palladium(II) with 3-amino-4-(arylazo)-5-(1H)pyrazolones (Aryl=Ph, 4-C6H4CO2H, 4-C6H4-OMe, 3-C6H4Cl, 3-C6H4CO2H, 3-C6H4NO2, 3-C6H4-Me, 3-C6H4OH and 2-C6H4CO2H) are discussed. The stoichiometry of the complexes is: 1∶1, 2∶3 CoII; 1∶1 NiII; 1∶1, 2∶1 CuII and 1∶2 PdII. The investigations suggest rhombic symmetry with 4- or 5-coordinate CoII, square planar and tetrahedral configuration for NiII, tetrahedral CuII and square planar for PdII complexes. The complexes contain no anions.
