Complexes of gold(I) with a variety of unidentate and potentially chelating P-, As-, Sb-, and S-donor ligands have been characterised by analysis, 1H n.m.r., i.r., and u.v.–visible spectroscopy, and electrical conductivity. In the majority of cases, the gold atom is two co-ordinate, [AuX(L)] or [XAu(L′–L′)AuX](L = unidentate ligand, L′–L′= bidentate ligand, X = Cl, Br, or SCN), but a few examples of
通过分析,1 H nmr,ir和uv可见光谱和电导率表征了金(I)与各种未知的和潜在螯合的P-,As-,Sb-和S-供体配体的配合物。在大多数情况下,金原子是两个坐标,[AuX(L)]或[XAu(L'–L')AuX](L =相同的配体,L'–L'=齿状的配体,X = Cl,Br或SCN),但发现了一些可能的三配位实例,[AuXL 2 ]或[AuX(L'–L')]。对于双齿配体,主链的刚性似乎是促进螯合的关键因素。阳离子络合物[AuL 2 ] +的形成容易程度取决于溶剂的极性。
