rac-{[2-(Diphenylthiophosphanyl)ferrocenyl]methyl}trimethylammonium iodide chloroform monosolvate
Abstract
The title compound, [Fe(C5H5)(C21H24NPS)]I·CHCl3, is built up from a (ferrocenylmethyl)trimethylammonium cation, a iodine anion and a chloroform solvent molecule, all residing in general positions. The N atom of the ammonium group is displaced by 1.182 (2) Å from the plane of the substituted cyclopentadienyl (Cp) ring towards the Fe atom, whereas the C atom attached to the same Cp ring is slightly below this plane by −0.128 (2) Å. These deviations might result from weak agostic interactions between the two H atoms of the CH2 group and the Fe atom.
