Synthesis, characterization and thermal properties of palladium(II) complexes containing phenyltetrazole. Crystal structure of trans-[C40H64N8 O2PdCl2]

Abstract

The new 5-(n-alkoxyphenyl)-2-n-alkyltetrazole (L¹) and alpha,omega-bis-[5-(4-pentoxyphenyl)-2-alkanetetrazoles] (L²) ligands and their Pd(II) complexes have been synthesized. The X-ray diffraction study of the palladium complex with L¹ reveals a mononuclear structure in which the geometry of the Pd(L¹)2Cl2 chromophore is planar as required by the inversion center at the palladium atom, where each molecule of phenyltetrazole binds to the metal ion in a monodentate fashion via a Pd-N1 sigma-bond. For the palladium complex with L², a dinuclear structure ([Pd2(L²)2Cl4 ]) has been proposed on the basis of NMR and IR spectroscopy.
