Stable gold(III) complexes with thiosemicarbazone derivatives.
Novel thiosemicarbazonato complexes of gold(III) have been prepared from reactions of [Au(damp-C1,N)Cl2(damp- = 2-(N,N-dimethylaminomethyl)phenyl) or [NBu4][AuCl4] with 2-pyridineformamide thiosemicarbazones (HL). The thiosemicarbazones deprotonate and coordinate as mononegative, tridentate NNS ligands to gold to give [Au(Hdamp-C1)(L)]Cl2 or [AuCl(L)]Cl complexes. The organometallic damp- ligan...

The reaction of the ligand Et4todit (4,5,6,7-Tetrathiocino-[1,2-b:3,4-b']diimidazolyl-1,3,8,10-tetraethyl-2,9-dithione) with gold complexes leads to the dinuclear gold(I) complexes [{Au(C6F5)}2(Et4todit)] and [Au(Et4todit)]2(OTf)2, which do not contain any gold-gold interactions, or to the gold(III) derivative [{Au(C6F5)3}2(Et4todit)]. The crystal structures have been established by X-ray diffr...
متن کاملGold-xenon complexes.
The recent isolation of the metal ± xenon compound [AuXe4] ([Sb2F11] )2 (1)[1] raises a number of questions. The salt 1 is formed from Au2 , dissolved in HF/SbF5, in the presence of xenon. If the concentration of SbF5 is fairly high (ca. 0.5 mol SbF5 in 1 mol HF) 1 forms as the sole product in two crystallographically different modifications: a triclinic modification,[1] and a tetragonal modifi...
متن کاملGold(I)-Komplexe mit Aminliganden, II [1]. (Methylpyridin)-Komplexe von Gold(I) Gold(I) Complexes with Amine Ligands, II. Methylpyridine Complexes of Gold(I)
Gold(I) complexes of overall formula LAuCl (L = various methylpyridines) are non-con ducting in acetone. X-ray structure analyses show that the solid state structure of the cor responding complex 1 (L = 2-picoline) is molecular; the 3-picoline derivative 2 is however ionic (L2Au)+(AuCl2). 3-Picoline forms a molecular complex LAuC6F5 (3) and also the ionic (L2Au)+(SbF6)_ (4). Complexes 1, 2 an...
متن کاملBiologically-Active Gold(III) Complexes
A review is given of the background to and results of the succesful pharmacological testing of [AuX(2)(damp)] (X = Cl, OAc; damp = 2-Me(2) NCH(2)C(6) H(4)) against a range of microbes, fungi and tumouts, culminating in in vivo xenografts of ZR-1-75. These are the first fully evaluated gold(III) complexes. The activity and reactions of the diacetato-complex bear a resemblance to cisplatin, and s...
