Abstract
trans-Bis(triphenylphosphine)dicarbonyl(1,3-di-p-tolyltriazenido)rhenium(I) crystd. in triclinic space group P1, with a 15.62(1), b 14.25(1), c 12.48(1) Å, 66.34(4)°, 108.84(4)°, and 115.48(4)°; d.(calcd.) = 1.46 for Z = 2. The structure was refined to R = 0.056. At. parameters are given. The coordination about the Re atom is approx. octahedral. The triazenido ligand is coordinated to the metal atom in a bidentate mode with a N(1)-Re-N(3) angle of 57(1)° and a N(1)- N(2)-N(3) angle of 105(1)°. The Re-N(1) and Re-N(3) bond lengths are 2.21(1) and 2.18(1) Å and the N(1)-N(2) and N(2)-N(3) distances are 1.33(1) and 1.31(1) Å, resp. The entire Re-triazenido system is essentially planar, indicative of delocalization over the whole system.
