Abstract
The title dimer, bis[1-cyclopentadienyl-2-methyl-1-titana-3-trimethylsilyl- 2,3-dicarba-closo-hexaborane(6)], [Ti(C5H5)(C6H16B4Si)](2), reveals that th e centrosymmetric molecule consists of two bent-sandwich titanacarboranes b ridged by the B-H-Ti bonds. The average bond distances are Ti-B 2.445 (3), Ti-C(cage) 2.334 (2) and Ti-C(Cp) 2.376 (3) Angstrom, and the corresponding bond angles are Cp-Ti-Cp 163.2 (1) and Cp-Ti-Cb (Cb = C2B3 face) 139.9 (1) degrees; the Ti-H separations are 2.10 (2) and 2.19 (2) Angstrom.
