síntese e caracterização de complexos de paládio(II) e platina(II) contendo amina e dmso

Abstract

This work describes the synthesis and characterization of three new metal complexes of the type [Pd(L)2Cl2], [Pt(L)2Cl2] or [Pt(DMSO)(L)Cl2],being L the compound 1,4-benzodioxan-6-amine. The palladium(II) and platinum(II) complexes were characterized by elemental analysis, conductimetry, IV (ATR-FITR), UV-Vis, TG/DTA, mass spectrometry and 1H and 13C NMR. The elemental analysis data are in full agreement with the proposed formulations, indicating high purity of the synthesized compounds. Spectroscopic data indicate that the ligand coordinates to both metals via nitrogen atom present in its structure. IV spectra indicate that the palladium and platinum complexes have planar square geometries with trans isomerism. Tests of molar conductivity in methanolic solution or in dimethylsulfoxide suggest that the compounds are neutral.
