  摘要：

  The redox reaction between closo-1-Sn-2-(SiMe3)-3-(Me)-2,3-C2B4H4 (2) and TiCl4 in a molar ratio of 1:1 in a solvent mixture of dry benzene (95%) and THF (5%) at 25-degrees-C produces, in 73% yield, a previously unknown tin(IV) pi-complex, 1,1'-commo-Sn[2-(SiMe3)-3-(Me)-2,3-C2B4H4]2 (1), Which exhibits an unusual bent-sandwich geometry as confirmed by a single-crystal X-ray diffraction study. The (ring centroid 1)-Sn-(ring centroid 2) angle of 142.5-degrees in 1 is similar to the corresponding angles in (eta-5-C5H5)2Sn(II) (145.8-degrees) and (eta-5-C5Me5)2Sn(II) (144.1-degrees), and thus the bent geometry of 1 resembles those of the stannocene derivatives despite the formal 4+ oxidation sate of the central tin atom.
