rac-{2-(Diphenyl­thio­phosphor­yl)ferrocen­ylmeth­yl}dimethyl­ammonium diphenyl­dithio­phosphinate

摘要

2-(Diphenyl­thio­phosphino)dimethyl­amino­methyl­ferrocene is a key inter­mediate in the synthesis of various ferrocenyl ligands. During one such synthesis, the title compound, [Fe(C5H5)(C20H22NPS)](C12H10PS2), was isolated as a by-product. It is built up by association of (2-(diphenyl­phosphino)ferrocen­yl)meth­yl)dimethyl­ammonium cations and diphenyl­phosphino dithio­ate anions. N—H⋯S, C—H⋯S and C—H⋯π inter­actions link the anions and cations. Each anion–cation pair is linked two by two through C—H⋯π inter­actions, forming pseudo dimers.
