Structure and luminescent property of a zinc(II) complex assembled from 5-methylisophthalic acid and 1,2-bis-(4-pyridyl) ethane

A zinc(II) coordination complex [Zn(bpe)(mip)]·H2O (1), (H2 methylisophthalic acid, bpe = 1,2-bis-(4-pyridyl) ethane) has been synthesized and structurally characterized. Analysis of the structure by single-crystal X-ray reveals that the complex 1 presents a three-dimensional (3D) threefold interpenetrating network based on dmp units (a 3D uninodal 4-connected net with the Schlنfli symbol of (65.8)). The compound has been characterized by infrared spectroscopy, elemental analysis, thermogravimetric analysis and powder X-ray diffraction. Solid state emission spectrum of the compound has also been studied at room temperature.
