Chloro[([alpha]-dimethylamino[3]ferrocenophan-2-yl)diphenylphosphino]gold(I) Benzene Solvate

The title complex, chloro{[1,1'-(1-dimethylamino-1,3-propanediyl)-2-ferrocenyl]diphenylphosphino-P}gold(I) 1.5-benzene solvate, [AuCl(C₂₇H₂₈FeNP)].1.5C₆H₆, is the first gold(I) complex comprising a ferrocenophane ligand bearing phosphorus and nitrogen coordination sites. The Au atom is preferentially bound to the soft site, the P atom. The three P-Au-Cl atoms are almost in a straight line and no interaction between Au and N atoms is observed. There is little distortion of the ansa bridge and the conformation of the phenyl groups minimizes the steric contacts.
