μ-Sulfido-bis{[1,1′-bis(diphenylphosphanyl)ferrocene-κ2P,P′]gold} methanol monosolvate

Abstract

The gold complex in title compound, [Au2Fe(C17H14P)2S]·CH3OH, (I)·CH3OH, is closely similar to the previously reported (I)·2CHCl3, reported in the literature [Canales et al. (1996). J. Am. Chem. Soc. 118, 4839–4845]. Both crystallize in the monoclinic crystal systems but the space groups differ, P21/n for (I)·CH3OH compared to P2/n for (I)·2CHCl3. The two structures can be considered as polymorphs due to solvation differences. In (I)·CH3OH, all atoms of the methanol solvent molecule are disordered over two sets of sites with an occupancy ratio of 0.822 (12):0.178 (12). The crystal structure features O—H...S, C—H...S hydrogen bonds and C—H...π interactions that stack the complex molecules along the a-axis direction.
