Ruthenium complexes containing the hemilabile ligand PPh2(CH2)P(O)PPh2 (dppmO): reactivity towards CO and X-ray molecular structures of tcc-RuCl2(η2-dppmO)2 and mer-RuCl3(η1,η2-dppmO)2

Ruthenium (II) complexes with the hemilabile ligand Ph2PCH2P(O)Ph2 (dppmO) were obtained and characterized by means of two dimensional analysis 31P-31P gCOSY, 13C-1H HSQC, 1H-31P HMBC IR and cyclic voltammetry. Based on the resulting chemical shifts, coupling constants and correlations between 1H, 13C and 31P spectra it was possible to accurately define the complexes structures. The determination of the crystal structure by X-ray diffraction was obtained for tcc-RuCl2(η2-dppmO)2, and mer-RuCl3(η1,η2-dppmO)2.
