Experimental and DFT Study on the Compounds [PdCl2L2] (L = 4-methylpyrazole, 4-iodopyrazole)

Acta Chim Slov. 2015;62(3):662-71. doi: 10.17344/acsi.2014.1299.

Abstract

Theoretical molecular structures of the complexes [PdCl(2)(HmPz)(2)] (1) and [PdCl(2)(HIPz)(2)] (2) (HmPz = 4-methylpyrazole; HIPz = 4-iodopyrazole) were studied using B3LYP/DFT method. The new complex 2 and the complex 1 were synthesized and characterized by elemental analysis and IR spectroscopy. The calculated bond distances and angles showed that both compounds exhibited a slightly distorted square planar coordination environment around the palladium center. The theoretical IR spectra of C(s) symmetry (electronic state 1A') of the complexes agree well with the experimental data.
