 Title    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.

 Title    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.

 Title    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.

 Title    Indium Triiodide Complexes of Bis(diphenyIphosphino)ethane (dppe) and its Disulfide (dppeS2)  
 Abstract    Bis(diphenylphosphino)ethane (dppe) and its disulfide (dppeS2) react with two equivalents of indium triiodide to give high yields of the corresponding 1:2 adducts. According to crys­ tal structure determinations, both compounds are molecular bis-terminal complexes with the ligands in an all-trans conformation. Contrary to previous findings for complexes of the indium trihalides and of G aB r3 and G al3 with ditertiary phosphines in fixed cis-structure [bis(diphenylphosphino)ethene or -benzene], no iodide redistribution is observed to give the ionic species [(dppe)Inl2]+ [InL ]-. The molecular structures are also retained in solution.

 Title    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.
