摘要

1:1四氯化鈦戊二腈與1:1四氯化錫戊二腈之構造在此論文中加以比較：兩者都是一維高分子形式，以戊二腈居間連接四氯化鈦或四氯化錫，而過渡金屬原子周遭環境為正八面體配位，氮原子居於順式構型。戊二腈保有TT形狀。1:1四氯化錫戊二腈之構造比起1:1四氯化鈦戊二腈之構造，在分析時要求數據標準較低，故兩者是不是相同晶體構造，仍有待重新將1:1四氯化錫戊二腈再次進行構造分析才能決定。

並列摘要

The structures of 1:1 TiCl_4-NC(CH_2)_3CN and 1:1 SnCl_4-NC(CH_2)_3CN are compared: both are in the form of a one-dimentional polymer with the glutaronitrile acting as a bridging ligand between titanium(IV) chloride or tin(IV) chloride units, respectively, while the transition metal atoms are octahedrally coordinated, with the nitrogen atoms in the cis configuration. The glutaronitrile has the TT conformation. Because the structure of 1:1 SnCl_4NC(CH_2)_3CN has been solved at a much lower significance than that of TiCl_4-NC(CH_2)_3CN has, whether or not the two structures are isomorphous needs a redetermination for the structure of 1:1 SnCl_4-NC(CH_2)_3CN.
