A Homochiral Coordination Polymer Based on Copper(II), S-Malic Acid, and Biphenyl-3,3,5,5-Tetracarboxilic Acid

The [Cu-8(S-mal)(4)(bptc)(H2O)(12)] 0.5H(4)bptc 7.5H(2)O coordination polymer is obtained by heating the copper(II) nitrate, S-malic acid (H(3)mal), and biphenyl-3,3,5,5-tetracarboxylic (H(4)bptc) acid solution in the water-N,N-diethylformamide mixture. The crystal structure is determined from XRD data. The compound has a three-dimensional homochiral framework with channels filled by crystallization molecules of tetracarboxylic acid and water. The composition and structure of the coordination polymer obtained are confirmed by X-ray powder diffraction, IR spectroscopy, thermogravimetric analysis, and elemental analysis.
