Binuclear Complexes of Ruthenium with Diphosphines and Bridging Benzene-1,2-diamide. X-Ray Crystal Structure of (CO)2(PPh3)2>*C6H5Me
The binuclear complex (CO)4(PPh3)2> 1 reacts with the diphosphines (Ph2P)2X , in boiling toluene, to give purple solutions from which the yellow compounds (CO)3(PPh3)(diphosphine)> -(mu-dppm)(CO)2(PPh3)2> 7 as the unique product.All these new complexes can be obtained in good yields by reaction of with in boiling mesitylene.Compound 1 also reacts with (PPh3)3> or in boiling xylene to give (CO)3(PPh3)3> 8 which easily regenerates 1 by reaction with CO.An excess of diphosphine (except for dppm) in the reaction with 1 produced the mononuclear complexes (CO)(diphosphine)> and and for the reaction with dppb the complexes (CO)3(dppb-P)(dppb-PP’)> 9, 10, (CO)2(dppb)2> 11 and 12 were also detected or isolated.All complexes have been characterized by elemental analysis and by IR and NMR spectroscopy.The structure of the toluene solvate of 7 has been determined by X-ray diffraction methods: monoclinic, space group P21/n, with a = 18.563(8), b = 21.066(9), c = 17.936(7) Angstroem, beta = 110.47(2) deg and Z =4.The structure was solved from diffractometer data by Patterson and Fourier methods and refined by full-matrix least squares to R = 0.0524 for 6679 observed reflections.The two Ru atoms are doubly bridged by the nitrogen atoms of 1,2-diimine ligand with a short Ru-Ru separation, 2.562(1) Angstroem, consistent with a metal-metal bond.
