Authors:Narayan S Hosmane  Chong Zheng
Abstract:The title dimer, bis­1‐cyclo­penta­dienyl‐2‐methyl‐1‐titana‐3‐tri­methylsilyl‐2,3‐dicarba‐closo‐hexaborane(6)], Ti(C5H5)(C6­H16­B4Si)]2, reveals that the centrosymmetric mol­ecule consists of two bent‐sandwich titanacarboranes bridged 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) Å, and the corresponding bond angles are Cp—Ti—Cp 163.2 (1) and Cp—Ti—Cb (Cb = C2B3 face) 139.9 (1)°; the Ti—H separations are 2.10 (2) and 2.19 (2) Å.
