Another type of neutral gold( I) complex is [ AuX(P R3)[ where X is an anionic oxygen or nitrogen donor ligand such as [Au N(S02CF3)2 (PR3)] or [Au(OR)(PR3)] or even [Au(OS02CF3)(PR3)[, which are relevant as catalytically-active species or catalytic precursors [26, 108]. 

The only simple oxo complex of gold(I) appears to be CsAuO, which is isostructural with KAgO and therefore contains Au404- units.7,167 Most other complexes contain a tertiary phosphine ligand on gold(I), and all are reactive compounds since gold(I) has little affinity for oxygen donors. 

As well as complexes containing only oxygen donors, there are several gold(UI) complexes with mixed 0,N donors. These are typically prepared by substitution of [AuCLJ- with the appropriate ligand. Some examples are (60)-(63). 18,519...
