The solvent-free, Pt-catalyzed desilylative coupling reaction of 1,1 0 -bis(dimethylsilyl)ferrocene (12) at elevated temperature leads to the elimination of one dimethylsilane unit and the concomitant oligomerization of ferrocenes with a single dimethylsilyl bridge in low to moderate yields. Airand moisture-stable oils of the dimer (13) and trimer (14) species possessing dimethylsilyl bridges and terminal dimethylsilane end groups have been isolated by preparative TLC and characterized by HR-MS, elemental analysis, and NMR spectroscopy.Polymetallocenes comprised of a repeat unit of ferrocene and a single heteroatom (e.

The title mol­ecule, [Sn(C8H3F6)4], lies on a twofold rotation axis with the SnIV ion in a distorted tetra­hedral coordination environment. Both –CF3 groups attached to one of the unique benzene rings are disordered over two sets of sites, with the ratios of refined occupancies being 0.719 (14):0.281 (14) and 0.63 (5):0.37 (5).
