摘要：

The three closely-related compounds [Ti((NPr)-Pr-i)Cl-2(NHMe2)(2)] 1, [Ti(NC6H5)Cl-2(NHMe2)(2)] 2 and [Ti(NC6F5)Cl-2(NHMe2)(2)] 3 all crystallize in the space group C2/c with the titanium atoms lying on two-fold axes at (0, y, 1/4); in compounds 1 and 2 the molecules are linked in one-dimensional infinite chains by intermolecular Ti-Cl . . .H-N hydrogen bonds along the direction of the crystallographic c axis, whereas in 3 offset face-to-face interactions between the C6F5 rings break down the hydrogen bonded chains.
