  Treatment of the ligand system (ο-C₆H₄OH)-S-CH₂-CH₂-S-(ο-C₆H₄-OH) (2a) with TiCl₄ gave the metalla-crown ether derivative [(-S-CH₂-CH₂-S-)(ο-C₆H₄O)₂]TiCl₂ (5a). Complex 5a was characterized by an X-ray crystal structure analysis. It showed a pseudo-octahedral structure with both sulfur atoms being cis-coordinated to the metal center. The chloride ligands are also cispositioned, whereas the remaining two Ti−oxygen bonds are trans to each other to complete the distorted octahedral coordination geometry. The reaction of 2a with ZrCl₄ gave the analogous complex 5c. The related ligand system (ο-C₆H₄OH)-O-CH₂-CH₂-O-(ο-C₆H₄OH) (2b) was doubly deprotonated by treatment with butyl lithium and then reacted with TiCl₄ to yield the complex [(-O-CH₂-CH₂-O-)(ο-C₆H₄O)₂]TiCl₂ (5b).

  用TiCl4处理配体系统(ο- OH)-S-CH2- -S-(ο-C6H4-OH)(2a)产生了metalla-crown ether衍生物[(-S- - -S-)(ο- O)2]TiCl2(5a)。通过X射线晶体结构分析表征了复合物5a。它显示出一个伪八面体结构，两个硫原子都与金属中心顺式配位。氯配体也是顺位排列的，而其余两个Ti-氧键则相互反向以完成扭曲的八面体配位几何。2a与ZrCl4的反应产生了类似的复合物5c。与此相关的配体系统(ο- OH)-O- - -O-(ο- OH)(2b)经过丁基锂处理后被双重去质子化，然后与TiCl4反应产生了复合物[(-O- - -O-)(ο- O)2]TiCl2(5b)。
