A new rhenium nitrosyl complex has been synthesized and characterized by IR, electronic and "P NMR spectroscopy and magnetochemical measurements. Its electronic structure has been determined (Dq = 3333, Ds = -4732 and Dt = 387 cm-'). The crystal and molecular structure of [ReCI3(NO)(OPPh&] has been solved by the heavy atom method and refined anisotropically to R =0.466 for 3032 unique observed reflections. The title compound crystallizes in the monoclinic space group C2/c, with a = 13.887(2), b= 13.154(2), c = 19.629(4)A, p=96.78(2)" and Z = 4. The Re atom is of six-coordinate distorted octahedral configuration and the linear nitrosyl ligand is trans to one of triphenylphosphine oxide molecules. The OPPh3 groups of [ReCI3(NO)(OPPh3)2] are in cis positions.
