    Notes: The reaction between (tht)AuCl (tht = tetrahydrothiophene) and neat pyrrolidine (L) leads to the compound L4Au3Cl3. An X-ray structure determination reveals the presence of molecules LAuCl and ions L2Au+ and Cl-, in the ratio 2:1:1. The packing is characterised by Au.Au contacts and N-H-Cl-hydrogen bonds.

    Synthesis and Structural Characterization of Gold(I) and Silver(I) Complexes of the Multidonor Ligand 2-(Phenacylthio)pyridine - Crystal Structures of [(AuPPh3){py{SCH2C(O)Ph}-2}](ClO4) and [(AgPPh3)(OClO3){py{SCH2C(O)Ph}-2}] (1998)

    Notes: The ligand properties of 2-(phenacylthio)pyridine towards gold(I) and silver(I) have been investigated. From the reactions of the ligand with acetone solutions of [M(PPh3)(acetone)]ClO4 (M = Ag, Au) under various experimental conditions, complexes [(AuPPh3)n{py{SCH2C(O)Ph}-2}](ClO)n, and [(AgPPh3)n(OClO3)n{py{SCH2C(O)Ph}-2}](n = 1-3) have been obtained. The crystal structures of the complexes [(AuPPh3){py{SCH2C(O)Ph}-2}]ClO4 and [(AgPPh3)(OClO3){py{SCH2C(O)Ph}-2}] have been determined by X-ray diffraction. In the cationic gold complex the metal is linearly coordinated to nitrogen and phosphorus, whereas the corresponding silver complex displays a trigonal planar geometry with pyridine, phosphane and perchlorato ligands.

    Synthesis of Gold(I) and Gold(II) Complexes with Diphenyl(trimethylsilylmethyl)phosphane (1998)

    Notes: The reaction of diphenyl(trimethylsilylmethyl)phosphane with [AuCl(tht)] affords the gold(I) complexes [AuCl(PPh2-CH2SiMe3)] (1) or [Au(PPh2CH2SiMe3)2]Cl (2). An X-ray study of 1 does not reveal any Au···Au interaction. Treatment of [Au(tht)2](CF3SO3) or [Au(tht)(PPh3)](CF3SO3) with diphenyl(trimethylsilylmethyl)phosphane results in the displacement of the thioether ligands to give the ionic complexes [Au(PPh2CH2SiMe3)2](CF3SO3) (3) or [Au(PPh2-CH2SiMe3)(PPh3)](CF3SO3) (4), the latter mixed with the symmetrical derivatives [Au(PPh2R)2](CF3SO3) (R = Ph, CH2-SiMe3). The molecular structure of complex 3 has been established by X-ray diffraction and shows an antiperiplanar arrangement of the two PR2R rotors in the solid state. The reaction of the phosphane ligand with [Au2{μ-(CH2)2-PPh2}2(tht)2](ClO4)2affords the dinuclear gold(II) complex [Au2{μ-(CH2)2PPh2}2(PPh2CH2SiMe3)2](ClO4)2 (5).

    Description / Table of Contents: Polysulfonylamines. LXXX [1]. Synthesis and Crystal Structures of Gold(I) Complexes with Disulfonylamide LigandsComplexes of the type Ph3PAuL (L = disulfonylamide ligand) can be conveniently prepared from Ph3PAuX (X = halide) and the corresponding silver disulfonylamide. Crystal structure determinations of four such complexes show the following common features: (i)The coordination at gold is linear; (ii)no short intermolecular contacts are observed; (iii)the gold atoms display two intramolecular Au … O contacts to L; (iv)the S-N bond lengths correspond to bond orders of ca. 1.4.
    Notes: Komplexe der Form Ph3PAuL (L = Disulfonylamid-Ligand) lassen sich bequem aus Ph3PAuX (X = Halogenid) und dem entsprechenden Silber-Disulfonylamid synthetisieren. Kristallstrukturbestimmungen von vier solchen Komplexen zeigen folgende gemeinsame Merkmale: (i) Die Koordination am Gold-Zentrum ist linear; (ii) keine kurzen intermolekulare Kontakte werden beobachtet; (iii) es gibt kurze intramolekulare Kontakte zwischen Gold und je zwei Sauerstoffatomen von L; (iv) die S-N-Bindungslängen entsprechen einem Bindungsgrad von ca. 1,4.
