Formation and X-ray crystal structure determination of the novel triplatinum cluster [(Ph3P)Pt(μ-SiC12H8)]3 from reaction of silafluorene with (Ph3P)2Pt(η2-C2H4)

Reaction of silafluorene (H2SiC12H8) with (Ph3P)(2)Pt(eta(2)-C2H4) in C6D6 (or C7D8) provided the trinuclear complex [(Ph3P)Pt(mu-SiC12H8)](3) (3). The structure of 3, which exhibits a nonplanar Pt3Si3 core, was confirmed by X-ray crystallography.
