 Title    Phosphinsubstituierte Chelatliganden, XIV [1] Wasserstoff-Brückenbindung in THF-Addukten von Tetracarbonylchrom-und -molybdänkomplexen mit P,S-koordinierten Phosphinothioformamid-Liganden. Kristallstruktur von [(CO) 4 Cr(PPh 2 C(S)NHMe)] THF Phosphine-Substituted Chelate Ligands, XIV [1] Hydrogen Bonding in THF-Adducts of Tetracarbonylchromium and -molybdenum Complexes with P,S-Coordinated Phosphinothioformamide Ligands. Crystal Structure of [(CO) 4 Cr(PPh 2 C(S)NHMe)] * THF  
 Abstract    The tetracarbonyl chromium and molybdenum P,S-chelate complexes la, b and 2a, b are obtained by low-temperature photolysis of the metal hexacarbonyls with the neutral phos-phinothioformamide ligands, Ph 2 PC(S)NHR (R = Me (a), Ph (b)), as stoichiometric 1/1 THF adducts. A weak N-H---O(THF) hydrogen bond is deduced from the ; H NMR spectra which show a collapse of the N-methyl doublet in la (T c -18 °C) but not in 2a. Unusually small P-C(S) couplings are observed in the 13 C{'H} NMR spectra. The N-methyl chromium complex la crystal-lizes in the triclinic space group P1 (Z = 2) with the lattice constants a = 1076.6(3), b = 1235.8(3), c = 915.1(3) pm, a = 97.99(4)°, ß = 92.73(5)°, y = 87.63(5)°. The planar thioamide unit adopts the Z configuration and is linked to the tetrahydrofuran molecule by a hydrogen bond (N-H1-031 164°) with an 0---H contact distance of 191 pm.
