The three closely-related compounds [Ti(NiPr)Cl2(NHMe2)2] 1, [Ti(NC6H5)Cl2(NHMe2)2 ] 2 and [Ti(NC6F5)Cl2(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 TiâClâ¯HâN 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.
三种密切相关的化合物 [Ti(NiPr)Cl2(NHMe2)2] 1、[Ti(NC6H5)Cl2(NHMe2)2 ] 2 和 [Ti(N )Cl2(NHMe2)2 ] 3 均在空间群中结晶C2/c,其中
钛原子位于 (0, y, 1/4) 处的二重轴上;在化合物 1 和 2 中,分子通过分子间 Ti-Cl-H-N 氢键沿晶体 c 轴方向连接成一维无限链,而在 3 中,分子间抵消了面对面的相互作用。
