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

Resumo

The [Cu₈(S-mal)₄(bptc)(H₂O)₁₂] · 0.5H₄bptc · 7.5H₂O coordination polymer is obtained by heating the copper(II) nitrate, S-malic acid (H₃mal), and biphenyl-3,3′,5,5′-tetracarboxylic (H₄bptc) 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.
