This paper presents the synthesis and characterization of two new type
s of Ru(II) complexes with R3P, R3PO, R3PS, R3PSe (R = tolyl) ligands.
Elemental analysis, UV, VIS and IR spectroscopy were employed to esta
blish the structure of the complexes studied, a tetragonal structure w
as assigned to [Ru(PR3)4Cl2] and a cubic structure to Ru2Cl4(PR3)6.
