Аннотация

A new tetranuclear zinc(II) complex [Zn4(tmphen)4(tbip)4(H2O)4] (1, tmphen = 3,4,7,8-tetramethyl-1,10-phenanthroline, H2tbip = 5-tert-butyl isophthalic acid) is hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction, elemental analysis, and IR spectroscopy. In complex 1, four tbip2– ligands act as bridges between four neighboring Zn atoms to form an unusual tetranuclear zinc cluster. The clusters are further connected by two types of O—H⋯O and C—H⋯O hydrogen bonds, generating a three-dimensional supramolecular structure. Meanwhile, π—π stacking interactions and C—H⋯p interactions further consolidate the three-dimensional supramolecular framework of 1. In addition, the luminescence measurements reveal that complex 1 exhibits strong fluorescent emissions in the solid state at room temperature.
