dc.description.abstract | Polynuclear silver(I) and gold(I) complexes with 2,5-bis(diphenylphosphinomethyl)thiophene (dpmt) [Ag2(μ-dpmt)3]-[BPh4] 2·2MeCN 1, [Ag2Cl2(μ-dpmt)] 2, [Ag3Br3(μ-dpmt)2] 3, [Ag3I3(μ-dpmt)2] 4, [Au2Cl2(μ-dpmt)] 5, [Au2Cl2-(μ-dpmt)2] 6, [Au2Cl2(μ-dpmt)3] 7 and [(Au2S)(μ-dpmt)] 8 were synthesised and 1,4,5 and 8 structurally characterised by X-ray crystallography. Complex 1 consists of a binuclear triple-helical [Ag2(μ-dpmt)3] cation with two three-co-ordinated AgI bridged by three dpmt ligands in a staggered-conformation with respect to the two AgP3 moieties. Complex 4 has a 'three-runged ladder' Ag3(μ3-I)(μ-I)2 unit which is bridged by two dpmt ligands above and below the trinuclear plane. Two of the AgI are tetrahedrally co-ordinated and one, in the middle of the structure unit, has trigonal co-ordination geometry. In 5, a pair of AuCl is bridged by one dpmt in which both AuI exhibit linear, two co-ordinated geometry. Complex 8 has a binuclear cyclic structure with a narrow Au-S-Au angle of 86.2(1)° and short Au⋯Au distance of 3.131(1) Å indicating a certain amount of intra-molecular Au⋯Au interaction. | |
