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

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.

Synthesis, characterization, and cytotoxic activity of novel platinum (II) complexes derived from n-benzyl-ethylenediamine and oxalate.

This work describes the synthesis and characterization of three novel complexes derived from N-benzyl-ethylenediamine and oxalate. Precursor compounds were synthesized by reacting N-benzyl-ethylenediamine with K(2)PtCl(4). Subsequent substitution of chlorides by oxalate led to the final products.
