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 2-(amino)-1-cyclopentene-1-dithiocarboxylato-kappa N,kappa S)-carbonyl(triphenylphosphine)rhodium(I)

The crystal structure of (methyl 2-(amino)-1-cyclopentene-1-dithiocarboxylato-kappa N,kappa S)-carbonyl(triphenylphosphine)rhodium(I), [Rh(hacsm)(CO)(PPh3)], was determined. The complex crystallizes in the monoclinic space group P2(1)/c with a = 16,430(1), b = 9.930(1), c = 17.194(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 with donor atoms L,L': variations of oxygen, nitrogen and sulphur). A good correlation between(1)J(P-31-Rh-103) and the Rh-P bond distance was obtained. (C) 1997 Elsevier Science S.A.
