摘要

在标题化合物di-μ-acetato-κ(2)O:O;κ(2)O:O'-bis[(6-氯-2-{(E)-[(pyridin-2-yl)甲基]methyl phenolato-κ(3)N,N'，O)zinc(II)]， [Zn2(C13H10ClN2O)2(C2H3O2)2]·CHCl3中，Zn(II)阳离子采用五坐标几何结构，由一个三叉状6-氯-2-{(E)-[(pyridin-2-yl)甲基]甲基苯酚配体的两个N原子和一个O原子以及两个桥接乙酸基的两个O原子配位，但它们的配位几何形状不同。一种Zn(II)阳离子为畸变三角双锥体几何，另一种为方锥体几何。两个醋酸配体以单齿和双齿配位方式桥接两个Zn(II)阳离子。该化合物在325 nm处激发后，在460 nm处有强发射，量子产率为23.1%。

Different Zn(II) cation coordination geometries in di-μ-acetato-bis{2-chloro-6-[(pyridine-2-ylmethylimino)methyl]phenol}dizinc(II) chloroform monosolvate.

In the title compound, di-μ-acetato-κ(2)O:O;κ(2)O:O'-bis[(6-chloro-2-{(E)-[(pyridin-2-yl)methylimino]methyl}phenolato-κ(3)N,N',O)zinc(II)], [Zn2(C13H10ClN2O)2(C2H3O2)2]·CHCl3, the Zn(II) cation adopts a five-coordinate geometry and is coordinated by two N atoms and one O atom of a tridentate 6-chloro-2-{(E)-[(pyridin-2-yl)methylimino]methyl}phenolate ligand and two O atoms of two bridging acetate groups, but their coordination geometries differ. One Zn(II) cation adopts a distorted trigonal bipyramidal geometry and the other a square-pyramidal geometry. The two acetate ligands bridge two Zn(II) cations with mono- and bidentate coordination modes. The title compound exhibits a strong emission at 460 nm upon excitation at 325 nm with a quantum yield of 23.1%.

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.
