Summary

The nitrogen-donor ligands 1-methylbenzotriazole (1Mebta), 5-methylbenzotriazole (5MebtaH), 5-chlorobenzotriazole (5ClbtaH) and 5-nitrobenzotriazole (5NO2btaH) react with palladium(II) and platinum(II) to give cis-[PdL2Cl2], cis-[PtL2Cl2] (L = 1Mebta, 5MebtaH, 5ClbtaH or 5NO2btaH), [Pt(5ClbtaH)4]Cl2, [Pd-(5MebtaH)Cl2]2, [Pd(5ClbtaH)Cl2]2 and [Pd(5NO2btaH)-Cl2]2. The complexes were characterized by physicochemical and spectroscopic methods. The benzotriazoles act as monodentate ligands binding through N(3). Monomeric square planar structures are assigned for the 1∶2 complexes and [Pt(5ClbtaH)4]Cl2 in the solid state. Centrosymmetric, chloro-bridged, dinuclear square planar structures of C2h symmetry are proposed for the 1∶1 palladium(II) compounds.
