摘要

氯基{μ-2-[(2-氧化双酶基)氨基]乙醇-κ(4)O,N,O':O'}{2-[(2-氧化双酶基)氨基]乙醇-κ(3)O,N,O'}三乙烯基二丁(IV)， [Sn2(C2H3)3(C9H9NO2)2Cl]在178 K以上呈无序结构。在冷却时观察到单胞体积增加了一倍。在93 K时，不对称单元包含两个有序分子。相转变对应于一个乙烯基与Sn(IV)原子结合的有序-无序转变。

Enantiotropic phase transition in a binuclear tin complex with an O,N,O'-tridentate ligand.

The crystal structure of chlorido{μ-2-[(2-oxidobenzylidene)amino]ethanolato-κ(4)O,N,O':O'}{2-[(2-oxidobenzylidene)amino]ethanolato-κ(3)O,N,O'}trivinylditin(IV), [Sn2(C2H3)3(C9H9NO2)2Cl], is disordered above 178 K. A doubling of the unit-cell volume is observed on cooling. The asymmetric unit at 93 K contains two ordered molecules. The phase transition corresponds to an order-disorder transition of one vinyl group bound to the Sn(IV) atom.

期刊介绍： Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
