A series of triorganophosphinegold(1) dithiocarbamate (R(3)PAuS(2)CNR'(2)) and xanthate (R(3)PAuS(2)COR') complexes have been prepared and characterised spectroscopically. Based on crystallographic evidence, the molecules feature linear gold(1) geometries defined by sulphur and phosphorus donors. The complexes, along with a series of known anti-cancer(More)
In the title compound, [Au(C(9)H(9)N(2)O(3)S)(C(6)H(15)P)], two virtually identical mol-ecules comprise the asymmetric unit. These are connected by Au⋯Au [3.6796 (4) Å] and Au⋯S [3.6325 (18) and 3.5471 (18) Å] contacts, forming a dimeric aggregate. The presence of intra-molecular Au⋯O contacts [2.993 (5) and 2.957 (5) Å] is responsible for the slight(More)
In the title compound, [Au(C(10)H(11)N(2)O(3)S)(C(18)H(33)P)], the gold(I) atom is linearly coordinated within a SP donor set. The distortion from linearity [S-Au-P = 177.54 (3)°] can be traced to an intra-molecular Au⋯O contact of 3.009 (3) Å. In the crystal, layers of mol-ecules are stabilized by a combination of C-H⋯O and C-H⋯π inter-actions.
X-ray crystallography shows the gold atoms in [R3PAu{SC(OMe)=NC6H4NO2-4}] (R = Et, Cy, Ph; 1-3, respectively) and [(Ph2P-R-PPh2){AuSC(OMe)=NC6H4NO2-4}(2)] (R = CH2, (CH2)2, (CH2)3, (CH2)4, Fc; 4-8, respectively) are linearly coordinated by phosphorus and thiolate-sulfur; weak intramolecular Au...O interactions are featured in all structures. The smaller(More)
The binuclear title compound, [Au(2)Fe(C(9)H(10)NOS)(2)(C(17)H(14)P)(2)]·CH(2)Cl(2), which has the Fe atom located on a crystallographic centre of inversion, crystallizes as a 1:1 dichloro-methane solvate, which is disordered about a centre of inversion. There is a small deviation from linearity defined by the SP donor set [S1-Au-P1 angle is 175.35 (5) °](More)
The dinuclear title mol-ecule, [Au(2)Fe(C(10)H(11)N(2)O(3)S)(2)(C(17)H(14)P)(2)]·2CHCl(3), has crystallographic twofold symmetry with the Fe atom (bonded to two η(5)-cyclo-penta-dienyl rings) situated on the rotation axis. The Au atom exists within a linear geometry defined by an S,P-donor set with a deviation from linearity [S-Au-P = 176.86 (6)°] due to(More)
An S,P-donor set in the title solvate, [Au(C(9)H(9)N(2)O(3)S)(C(18)H(15)P)]·CH(2)Cl(2), defines a linear geometry for the Au(I) atom [S-Au-P = 177.75 (7)°], with the minor distortion ascribed to the influence of an intra-molecular Au⋯O contact [3.019 (6) Å]. In the crystal, the packing is stabilized by a network of C-H⋯S, C-H⋯N and C-H⋯O contacts.
Each gold atom in the binuclear title compound, [Au(2)(C(9)H(9)N(2)O(3)S)(2)(C(25)H(22)P(2))], is coordinated within an S,P-donor set that defines a slightly distorted linear geometry [S-Au-P angles = 172.77 (6) and 173.84 (6)°], with the distortion due in part to a close intra-molecular Au⋯O contact [2.968 (11) and 2.963 (4) Å]. The mol-ecule adopts a(More)
