| Austauschreaktionen an komplexgebundenen Liganden Darstellung und Reaktionen von Komplexen des Typs 7r-C5H5Mn(CO)2L (L = Phosphid, Amid) Preparation and Reactions of Complexes of the Type 7r-C5H5Mn(CO)2L (L = phosphide, amide)  | | | | Abstract
| The reduction of the complexes C5H5Mn(CO)2L (L = P(C6H5)2C1, P(C6H5)(Et)Cl and P(C6H5)C12) with Na in liquid NH3 yields the complexes C5H5Mn(CO)2L' (L' = P(C6H5)2Na, P(C6H5)(Et)Na and P(C6H5)Na2). The reaction of these complexes with CH3J and of CpMn(CO)2P02Na with H20, CH2C12, CCI4, J2 and CH3COCI are described. Furthermore it has been found, that «-butyl-lithium yields C5H5Mn(CO)2NMe2Li if reacted with C5H5Mn(CO)2NMe2H. | | | |

| ferf-Butylphosphin-Komplexe von Gold(I)-und Silber(I)-halogeniden te?^-Butylphosphine Complexes of Gold(I) and Silver(I) Halides | | | | Abstract
| From HAuCLi and tri-<er£-butyl phosphine in methanol the gold(I) complex [(CH3)3C]3P-Au-C1 (1) has been synthesized and converted into the bromide 2 and iodide 3, using KBr and KI, respectively, in acetone solvent. The corresponding P-Cl functional complexes [(CH3)3C]2PCl-AuCl (4) and (CH3)3CPC12 -AuCl (5) could be obtained from (carbonyl)gold chloride ClAu(CO) and the chlorophosphine in benzene, with evolution of CO. The di-£e^-butyl-phosphine analog, [(CH3)3C]2PH -AuCl (7) results from a low-temperature reduction of HA11CI4 with this phosphine. All these gold(I) complexes are soluble in many solvents as monomers. The corresponding silver compounds, prepared from [(CH3)3C]3P and AgCl, Br, I in an inert solvent, appear to be oligomers, however, and showed dimer or tetramer association in halocarbon or benzene solvent. Infrared and 1 H, 13 C, 31 P NMR spectra have been used for further characterization of the compounds. | | | |

| Vier-und fünffach koordinierte Organometall-Phosphankomplexe von Aluminium, Gallium, Indium und Thallium Four-and Five-Coordinate Organom etal Phosphine Complexes of Aluminum | | | | Abstract
| A The organom etal phosphine complexes M L3 (L = [o-(Ph2PCH2)C6H4]"; M = A l3+, G a3+, In3+) are obtained from MC13 and the lithiated ligand in diethyl ether. Tl[o-(Ph2PC H 2)C6H 4]3 is prepared from T1C1 by a disproportionation reaction. M 1 species could not be detected with L as ligand. Al[o-(Ph2PCH 2)C6H4]3 is the first triorganoaluminum bis(phosphine) adduct where C3P2 pentacoordination at aluminum has been definitely proven for both the solution (<5(27A1) = 131 ppm, w 1/2 = 12 kHz) and the solid state (d (A l-P) = 2.676(3)/2.782(2) Ä). The trigonal-bipyramidal coordination geometry (C3P2) at Al is achieved by two o f the anionic phosphines acting as chelating ligands, spanning equatorial (C atoms) and axial sites (P atom s), while the third phosphine is only carbon-bonded. Like A1L3, the heavier congeners M L3 (M = G a, In, Tl) are stereochemically nonrigid molecules in solution. Surprisingly, in the solid state only InL3 resembles the aluminum complex (C3P2 penta-coordination) while G aL 3 and T1L3 contain four-coordinate metal centers (C3P). This may be rationalized by the notice ably less polar G a -P bonds as compared to A l-P and I n -P bonds, while in T1L3 the span o f the ligand is not sufficient to allow for chelating coordination at a five-(or six-)coordinate Tl center. | | | |

| The Crystal Structure of [Bis(tri-'butyl-phosphine)gold(I)] Chloride | | | | Abstract
| The title compound is available from the reaction of labile gold(I) chloride com plexes and an excess of the ligand ('Bu3P), or from the N aBH 4 reduction of ('Bu3P)AuCl. It forms dark red cubic crystals, [a = 14.297(1) A at -5 6 °C, space group P2j3, Z = 4], with isolated chloride anions and [('Bu3P)2Au]+ cations of C3 symmetry, with linear two-coordinate gold centers. | | | |
