The crystal structures of a series of allyltitanium complexes have been determined by X-ray crystallography. Crystals of (C5H52Ti(1,3-dimethylalyl) (1) are monoclinic, space group P21/n, with a = 13.353(2), b = 7.674(1), c = 25.543(2) Å, β = 90.92(1)°, and Z = 8. Crystals of (C5H5)2Ti(2-methylallyl) (2_ are orthorhombic, space group Pbca, with a = 15.299(4), b = 25.797(2), c = 12.014(1) Å, and Z =
