This paper describes the synthesis of a series of diphenylphosphane and diphenylphosphanide gold(III) and gold(III)/gold(I) complexes with 3,5-C6Cl2F3 aryl ligands. The reactions of a new polymeric thallium(III) complex with different gold compounds result in the formation of these complexes. The crystal structures of some of these complexes have been determined.
In this paper, we describe a series of diphenylphosphane and diphenylphosphanide gold(III) and gold(III)/gold(I) complexes containing 3,5-C6Cl2F3 as aryl ligands at gold that have been synthesized due to the arylating and oxidant properties of the new polymeric thallium(III) complex [TlCl(3,5-C6Cl2F3)(2)](n) (1). Its reaction with [Au(3,5-C6Cl2F3)(tht)] (tht = tetrahydrothiophene) produces the gold(III) complex [Au(3,5-C6Cl2F3)(3)(tht)] (2), which allows the synthesis of the diphenylohosphane derivative [Au(3,5-C6Cl2F3)(3)(PPh2H)] (3). Its treatment with acetylacetonate gold(I) derivatives leads to two novel Au-III/Au-I phosphanido-bridged complexes, [PPN][Au(3,5-C6Cl2F3)(3)(mu-PPh2)AuCl] (4) and [PPN][{(3,5-C6Cl2F3)(3)Au(mu-PPh2)}(2)Au] (5). All these complexes have been characterized, and the crystal structures of 1, 2, 4 and 5 have been established by single crystal X-ray diffraction methods, showing a novel polymeric arrangement in 1.
