Chloro(triphenylphosphine)gold(I)

Abstract

Abstract. Chloro(triphenylphosphine)gold(I), (C6Hs)3PAuCI, prepared by reacting triphenylphosphine with chloroauric acid in alcohol, crystallizes in the orthorhombic space group P212~2~ with a= 12-300 (4), b= 13.084 (4), and c=10.170 (3) A; De= 1-991, Dm=l'97 g cm -3, Z=4, R2=0.037 based on 2109 reflections collected on a four-circle automated diffractometer. The molecule is linear with the goldphosphorus distance equal to 2.235 (3) A and the goldchlorine distance equal to 2.279 (3) A.

Structure of tetraphenylphosphonium bis(benzenethiolato)aurate(I), [P(C6H5)4][Au(C6H5S)2]

“…The coordination at the gold atom is linear as is expected for Au I complexes with few intraor intermolecular steric pressures. The S(1)-Au-S(2) angle of 179.0(3) may be compared with those observed in the similar complexes AuCIPPh 3 [/C1-Au-P, 179.68 (8) °] (Baenziger, Bennett & Soboroff, 1976) and AuC1P(OPh) 3 [/P-Au-P, 178.5(2) ° ] (Hitchcock & Pye, 1977). The two Au-S distances of 2.271 (8) and 2.262 (8)/k lie within the range observed (2.223-2.297/k) in a number of other Au I complexes with two S donors (Hesse & Jennische, 1972;Guy, Jones & Sheldrick, 1976;Ruben, Zalkin, Faltens & Templeton, 1974;Lawton, Rohrbaugh & Kokotailo, 1972).…”

Impedance technology reveals correlations between cytotoxicity and lipophilicity of mono and bimetallic phosphine complexes

“…In fact, the released THT moiety that is present in the reaction mixture filled the fourth coordination site in 1a by coordinating to palladium through the sulphur atom. The geometry around the gold center in 1a deviates from linearity, with a bond angle P1-Au1-Cl3 (170.09(2) o ) which deviates from linearity much more than the corresponding angle in (triphenylphosphine)gold(I) chloride (179.63(8)º) reported in the literature (Baenziger et al, 1976). …”
