35. Although accurate positions of hydrogen atoms are difficult to obtain by X-ray diffraction methods, the hydrogen atoms attached to C(7) and C(20) were located from the difference electron density map and refined isotropically. The short Ti⋯H distances (Ti(1)⋯H(7A) = 2.36(3) Å (molecule 1), Ti(2)⋯H(20A) = 2.33(3) Å (molecule 2)) also support the agostic interaction in the solid state.
