(R)-2-[(Dimethyl-amino)-meth-yl]-1,1'-bis-(diphenyl-phosphinothio-yl)ferrocene dichloromethane monsolvate.

ABSTRACT: In the title compound, [Fe(C(20)H(21)NPS)(C(17)H(14)PS)]·CH(2)Cl(2), both cyclo-penta-dienyl (Cp) rings constituting the ferrocene unit are substituted by a sulfur-protected diphenyl-phosphine. One of the Cp ligands is additionally substituted by a dimethyl-amino-methyl group causing the chirality of the mol-ecule. Surprisingly, although the synthetic procedure yielded the title compound as a racemic mixture, the reported crystal is enanti-omerically pure with the R absolute configuration. The dimethyl-amino group is exo with respect to the Cp ring. Both diphenyl-thio-phosphine groups are trans with respect to the centroid-Fe-centroid direction. Weak intra-molecular C-H?S and C-H?? inter-actions between symmetry-related mol-ecules are observed. The contribution of the disordered solvent was removed from the refinement using SQUEEZE in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155].
