(Ferrocenylthiophosphonato-κS)(triphenylphosphane-κP)gold(I) dichloromethane monosolvate

In the title compound, [AuFe(C5H5)(C5H5O2PS)(C18H15P)]·CH2Cl2, 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) , 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, intermolecular O—H...O hydrogen bonds link dinuclear molecules into chains propagated in the [010] direction. The dichloromethane solvent molecule was disordered between two positions in a 0.63 (3):0.37 (3) ratio.
