Abstract
Lapachol (lap) is widely studied due to its biological application, as well as its importance in the coordination chemistry field. The structure of cis and trans isomers of new ruthenium(III) complex [RuCl2(PPh3)2(lap)] is reported here. The complexes present one molecule of the natural product lapachol, coordinated as bidentate by oxygen atoms, two monodentate triphenylphosphines and two chlorido ligands in a cis or trans configurations. All neutral complexes were characterized by single-crystal X-ray diffraction and these data were compared with Density Functional Theory (DFT) data results. This study highlights the stereochemistry and structural versatility of metal complexes containing lapachol as ligand.
