Reaction of a bimetallic iron–tin cluster with group V donors

Abstract The reaction of di-iron nonacarbonyl with triphenyl stannane yielded the bow-tie structured Fe 4 (CO) 16 (μ 4 -Sn), 1 . 1 reacted with LPh 3 to afford the corresponding derivatives Fe 4 (CO) 15 (LPh 3 )(μ 4 -Sn), (L = P, 2 , L = Sb, 3 ) by CO substitution on Fe. 2 and 3 were characterized crystallographically by single-crystal X-ray diffraction techniques.
