STRUCTURAL CORRELATION BETWEEN RH-P AND RH-C BOND DISTANCES VS P-31 AND C-13 NMR PARAMETERS IN MONOCARBONYLPHOSPHINERHODIUM(I) COMPLEXES - CRYSTAL-STRUCTURE OF (METHYL -N,KAPPA-S)-CARBONYL(TRIPHENYLPHOSPHINE)RHODIUM(I)

The crystal structure of (methyl 2-(amino)-1-cyclopentene-1-dithiocarb oxylato-kappa N,kappa S)-carbonyl(triphenylphosphine)rhodium(I), [Rh(h acsm)(CO)(PPh3)], was determined. The complex crystallizes in the mono clinic space group P2(1)/c with a = 16,430(1), b = 9.930(1), c = 17.19 4(1)Angstrom, beta = 90.72(1)degrees, Z = 4, R = 2.89% from refinement of 3143 reflections. The structural data obtained by this study were correlated with P-31 and C-13 NMR data measured for different [Rh(L,L' -BID)(CO)(PPh3)] complexes (L,L'-BID = monocharged bidentate ligand wi th donor atoms L,L': variations of oxygen, nitrogen and sulphur). A go od correlation between(1)J(P-31-Rh-103) and the Rh-P bond distance was obtained. (C) 1997 Elsevier Science S.A.
