 Abstract    o f N itrene C om plexes w ith N -T rim ethylsilylaniline I. Characterisation and Crystal Structure o f [R e(N Ph)C l3(E t2PhP)2] and [Re(N Ph)Cl3(Ph3P)2] • 1/2CHC13 U rsula W ittern, Joachim Strähle*, U lrich A bram rra»^-mt'r-Trichlorobis(diethylphenylphosphine)phenylnitrene rhenium(V), [Re(NPh)Cl3-(Et2PhP)2], has been synthesized from [ReOCl3(Et2PhP)2] and N-trim ethylsilylaniline, while rrans-ttZfr-trichlorophenylnitrenebisCtriphenylphosphine) rhenium(V), [Re(NPh)Cl3(Ph3P)2] has been obtained via a novel route, from (Bu4N)[ReOCl4] and N-trim ethylsilylanilin. The products were studied by mass spectrometry, IR spectroscopy and X-ray diffraction. rrafls-m er-[Re(NPh)Ch(Et-'PhP)2] crystallizes in the m onoclinic space group P2i/n with a = 1498.5(3), b = 1068.6(1), c = 1784.0(4) pm and ß = 91.28(1)°, Z = 4. The rhenium atom exhibits a distorted octahedral coordination with the phosphine groups in trails positions, and the Cl ligands in a meridional arrangement. The R e = N -C moiety is linear with a bond angle o f 169,4(5)°and a R e = N bond length o f 171.8(6) pm.

The asymmetric unit contains two symmetry independent complex m olecules o f approxima­ tely the same structure, with Cl atoms meridionally arranged and the phosphine groups in trans positions. The coordination geometry is a distorted octahedron. The almost linear R e = N -C m oieties have R e = N bond lengths o f 170.2(7) and 170.8(7) pm, respectively, and R e -N -C angles o f 173.3(6)°and 175.0(7)°.
