Abstract

New heteroleptic zinc catecholate complexes based on 3,6-di-tert-butyl-o-benzoquinone and containing metal-coordinated N-donor ligands (2,2'-bipyridine and phenanthroline) were prepared by ligand exchange. According to X-ray diffraction data, both complexes were dimers with multiple intermolecular π–π interactions between the aromatic moieties of neighboring molecules (CCDC nos. 2222704 (I), 2222705 (II)). The electronic transmission spectra of crystalline samples of I and II and their solutions show broad absorption bands in the visible region with a maximum at about 500 nm.

杂配儿茶酚酸锌与 N-供体配体的配合物

摘要

通过配体交换制备了基于 3,6-二叔丁基-邻苯醌并含有金属配位 N-供体配体（2,2'-联吡啶和菲咯啉）的新型杂配儿茶酚锌配合物。根据 X 射线衍射数据，这两种复合物都是二聚体，相邻分子的芳香部分之间具有多个分子间 π-π 相互作用（CCDC 编号 2222704 ( I )、2222705 ( II )）。I和II晶体样品及其溶液的电子透射光谱在可见光区域显示出宽的吸收带，最大吸收带约为500 nm。
