Organoboron and organosilicon chemistry

A structural study of the complex (η5-C5H5)2Ti(μ-H)2AlCl2 · O(C2H5)2 (I) was carried out. The crystals are rhombic, a 12.322(2), b 15.090(3), c 37.941(7) Å; ϱcalcd 1.326 g/cm3, Z = 16, R1 = 0.071, R2 = 0.050. The unit cell of I involves two independent molecules of I. The immediate environment of the titanium atom involves two cyclopentadienyl moieties and two bridging hydrogen atoms occupying the vertices of a distorted tetrahedron. The coordination polyhedron at the aluminium atom is a distorted trigonal bipyramid, in which the axial positions are occupied by the bridging hydrogen atom and the oxygen atom (μ-HAlO angle 158°).
