 Title    Phosphinsubstituierte Chelatliganden, IV [1] Neue Diphenylphosphinoformamid-Komplexe des Mangans und Eisens Phosphine Substituted Chelate Ligands, IV [1] New Diphenylphosphino Formamide Complexes of Manganese and Iron  
 Abstract    The phosphino and (thio)phosphoryl formamides la, b, 2a-c, 3a, b, 4a, b which were partially unknown are synthesized by various methods, and their reactions with carbonyl-metal halides of manganese and iron are described. The formation of the P,N-and S,N-coordinate chelate complexes, (CO)4MnL (5 a, 8a), is limited to the N-phenyl derivatives la and 4a. With L = 2a, b, the unidentate P-coordination predominates. Thus, the carbonylmetal halide complexes cis-(CO)4Mn(X)L (6a, b: X = CI, 7a, b: X = Br) and 7? 5 -C5H5(CO)Fe(X)L (9a, b: X = I, 10a, b: X = Br) are obtained. Due to the low stability of the formamide complexes, their formation is always accompanied by isocyanate elimi-nation as a side-reaction.

 Title    Phosphinsubstituierte Chelatliganden, VI [1] Kristallstrukturen von Tetracarbonyl(diphenylphosphino -N-phenylthioformimidato -P,S )mangan(I) und Tetracarbonyl(diphenylthiophosphoryl-N-phenylthioformimidato-S,S')mangan(I) Phosphine Substituted Chelate Ligands, VI [1] Crystal Structures of Tetracarbonyl(diphenylphosphino-N-phenylthioformimidato-P,S)- manganese(I) and Tetracarbonyl(diphenylthiophosphoryl-X-phenylthioformimidato-S.S')- manganese(I)  
 Abstract    The phosphinothioformimidato complex (CO)4MnSC(NPh)PPli2 (1) crystallizes tri-clinic in the space group PI with lattice constants a = 989.4(9) pm, b — 1042.0(8) pm, c = 1088.5(8) pm, a = 91.45(4)°, ß = 97.10(4)°, y = 100.53(5)°. The four-membered chelate I 1 ring Mn-P-C-S is folded over the P-S edge by a dihedral angle of 167.1°. The crystal I 1 system of the thiophosphoryl thioformimidato complex (CO)4MnSC(NPh)P(S)Ph2 (2) is monoclinic with the space group P2i/c, and the lattice parameters are a = 1109.5(3) pm, b = 966.0(3) pm, c = 2256.7(3) pm, 0=103.11(2)°. The chelate ligand is linked to the metal by two S atoms forming a five-membered ring in the "envelope" conformation with the thiophosphoryl S atom at the apical position.
