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

• We investigated the reaction of a bimetallic iron–tin cluster Fe4(CO)16(μ4-Sn) with group V donors.
• Fe4(CO)16(μ4-Sn) reacts with PPh3 to afford the phosphine derivative Fe4(CO)15(PPh3) (μ4-Sn).
• Fe4(CO)16(μ4-Sn) reacts with SbPh3 to afford the trimetallic Fe4(CO)15(SbPh3) (μ4-Sn).
• The structures of the new complexes were characterized by single-crystal X-ray diffraction analysis.

The reaction of di-iron nonacarbonyl with triphenyl stannane yielded the bow-tie structured Fe4(CO)16(μ4-Sn), 1. 1 reacted with LPh3 to afford the corresponding derivatives Fe4(CO)15(LPh3)(μ4-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.

We have investigated the reaction of a bimetallic iron–tin cluster Fe4(CO)16(μ4-Sn) with group V donors. Fe4(CO)16(μ4-Sn) reacts with LPh3 to afford the phosphine derivative Fe4(CO)15(PPh3) (μ4-Sn), L = LPh3, or reacts with SbPh3 to afford the trimetallic Fe4(CO)15(SbPh3) (μ4-Sn), L = SbPh3. The structures of the new complexes were characterized by single-crystal X-ray diffraction analysis.Figure optionsDownload as PowerPoint slide
