(Ferrocenyl-thio-phospho-nato-κS)(triphenyl-phosphane-κP)gold(I) dichloro-methane monosolvate

In the title compound, [AuFe(C(5)H(5))(C(5)H(5)O(2)PS)(C(18)H(15)P)]·CH(2)Cl(2), the two-coordinate gold(I) atom shows a slightly distorted linear arrangement, with a P-Au-S bond angle of 176.81 (6)°. The difference in P=O and P-O(H) bond lengths, which are 1.503 (6) and 1.541 (5) Å, respectively, implies there is apparently no delocalization between the P-O bonds, and the proton appears to be localized on one O atom only. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link dinuclear mol-ecules into chains propagated in the [010] direction. The dichloro-methane solvent mol-ecule was disordered between two positions in a 0.63 (3):0.37 (3) ratio.
