 Title    Ligand Influences on the Supramolecular Chemistry of Simple Gold(I) Complexes: Mononuclear (Isonitrile)gold(I) Complexes  
 Abstract    A series of (isonitrile)gold(I) complexes has been synthesized: (MeNC)AuX (X = Cl la, I lc), (f-BuNC)AuBr 2b. (PhNC)AuX (X = Cl 3a. Br 3b. I 3c. SCN 3d), (MesNC)AuCl 4a [mes=mesityl], and (Me0 C(0)CH2NC)AuX (X = Cl 5a. Br 5b. I 5c. SCN 5d). The chlorides were prepared by the reaction of (M e2S)AuCl with equimolar amounts (or with an excess) of the corresponding isonitrile. The bromides, iodides and thiocyanates were obtained from the reaction of (RNC)AuCl with K+X -(X = Br, I, SCN) in the two-phase system H2O/CH2CI2. The molecular and crystal structures of la. 2b. 3a-c, 4a, and 5a-c have been determined by X-ray diffraction methods. In the solid state the molecules are aggregated through short A u-A u contacts into dimers (4a and 5c), chains (la , 2b and 3a-c) or sheets (5a and 5b). The influence of the isonitrile and halide ligands on the type and strength of the intermolecular A u-A u contacts is discussed. I n tro d u c tio n

 Title    Gold(I) Complexes of Chiral Secondary Phosphines  
 Abstract    The reaction of (dimethylsulfide)gold(I) chloride and bromide with methyl(phenyl)phosphine in tetrahydrofuran affords high yields of the colorless, crystalline, chiral complexes [M e(Ph)HP]AuCl/Br (la, b). Treatment of la with potassium iodide in thf leads to a conversion into the corresponding iodide [Me(Ph)HP] Aul (lc). The compounds were characterized by their analytical and spectroscopic data, and the crystal structures of la, b have been determined. The two compounds are isomorphous. In the lattice the monomers form chain-like supramolecular aggregates through auriophilic A u-A u contacts. The chains contain both enantiomers following the sequence . . R S R S R S.., with the individual components related by crystal symmetry.

 Title    Structural Investigation of Bis(isonitrile)gold(I) Complexes  
 Abstract    The reaction of (MeNC)-, (PhNC)-and (MesNC)AuCl in tetrahydrofuran with an equimolar amount of the corresponding isonitrile ligand and one equivalent of Ag+X~ (X -= BF^ or CF3S O J) leads to the formation of the bis(isonitrile)gold(I) complexes (MeNC)aAu+ CFiSO ^ (1), (PhNC)2Au+ BF^ (2) and (M esNC)2Au+ BF^ (3). The crystal structures of 1, 2 and 3 have been determined. In compound 1 there are rod-like cations with a parallel packing into meandering puckered layers, in which the gold atoms have alternating A u-A u contacts of 3.611 and 3.624 A. In complex 2 the cations form long double-paddles, with the two paddles at an angle of 11.5°. The individual cations are well separated and have no sub-van-der-Waals A u-A u contacts. The crystal structure of 3 is similar, but with a smaller dihedral angle between the planes of the two mesityl rings (56.0°).

 Title    (Triphenylarsine)gold(I) Complexes: Synthesis of an Oxonium Salt and Redistribution of the Arsine Ligands  
 Abstract    The reaction of [(Ph3As)AuCl] with Ag20 in the presence of NaBF4 in tetrahydrofuran affords three products, identified as [(Ph3As)4.Au]BF4 (40.3%), [(Ph3As)2Au]BF4 (16.4%) and {[(Ph3As)Au]3 0 }BF4 (17.3%). The properties of the main product agree well with recent literature data. The other two compounds are new and have been identified by their analytical, spectroscopic, and crystallographic data. The structures are isomorphous with those of the analogous Ph^P complexes. Variations in the stabilities are discussed in terms of kinetic and thermodynamic effects.

 Title    The Structural Chemistry of GoId(I) Quinoline-2-thiolate and Iodide Complexes of Polytertiary Phosphines  
 Abstract    Treatment of (chloro)gold(I) complexes of di-and tetra-tertiary phosphines with equivalent quantities of sodium quinoline-2-thiolate in methanol / dichloromethane affords the correspond­ ing (phosphine)gold(I) quinoline-2-thiolates in high yields. The di-and tetranuclear complexes, respectively, of a,u>bis(diphenylphosphino)-propane (1), -butane (2) and -pentane (3) and of tris(2-diphenylphosphino-ethyl)phosphine (4) have been obtained as crystalline solids, and the structures of 2 and 4 have been determined by single crystal X-ray diffraction studies. Un­ expectedly, the molecules of 2 are loosely aggregated into strings via weak intermolecular gold-sulfur, not via Au-Au interactions. Compound 4 is a monomeric tetranuclear cluster in the solid state with two intramolecular gold-gold bonds. Bis(2-diphenylphosphino-ethyl)-phenylphosphine (PPP) forms trinuclear complexes with gold(I) chloride, bromide and iodide (5a -c). The iodide complex features a chain structure through intermolecular Au -Au contacts between the two terminal P-Au-I units. The closest contacts between the chains are determined by Au-I and I -I interactions of the central P-Au-I unit.

 Abstract    Copper and Gold Complexes of Dithiocarbam ate Esters. X-Ray Structures of [CuC1(L1)3] ■ CH2C12, [A uC ^L 1^], [CuI(L1)(PPh3)]2 and [Cu2ICuIICl4(L2)2]n (L 1 = Reactions of N-phenyl-S-methyldithiocarbamate (L1) and N,N-dimethyl-S-methyldithio-carbamate (L2) with CuCl2, [CUjI^PPhj^] and HAuC14 yield the complexes [CuC1(L1)3] • CH2C12 (1), [AuCKL1),] (2), [CuI(L1)(PPh3)]2 (3) and [Cu2ICuIICl4(L2)2]" (4). Their structures have been determined by single crystal X-ray crystallography. 1 and 2 are monomeric, with Cu(I) tetrahedrally four-coordinate and Au(I) two-coordinate with an S-Au-S angle of 158.2(1)°. 3 is dimeric with a central CuI2Cu core, the Cu— Cu distance of which [314.9(1) pm] is rather large. The mixed valence complex 4 has a chain structure with the identity period CuI1(a-Cl)2CuI(a-S)2CuI(a-Cl)2. Cu1 is in a tetrahedral, Cu11 in a square planar environment. The (m-S)2 bridged Cu1---Cu1 distance is only 259.1(1) pm. The structures of the CuX2Cu cores of 3 and 4 are mainly determined by steric interactions of the donor atoms within the coordination spheres of the metal centers.
