Synthesis, crystal structure and thermal analysis of supramolecular architectures of copper(II)(2,2′-biimidazole) complexes using dicarboxylate as a coligand
چکیده انگلیسی

Two new copper(II) complexes {[Cu(H2biim)(H2O)(suc)](H2O)}n (1) and {[Cu(H2biim)2(H2O)][Cu(H2biim)2(glut)](glutH)(NO3) · 2.5H2O}n (2) (H2biim, 2,2′-biimidazole; suc, succinate dianion; glut, glutarate dianion) have been synthesized and characterized by single crystal X-ray diffraction study and thermal analysis. Complex 1 comprises of 1D zigzag coordination polymers, elongated along the crystallographic b-axis, connected through H-bonding and face-to-face π–π interactions to form a robust 3D network. Whereas complex 2 is built up of bischelated [Cu(II)(H2biim)2]2+ units, glutarate and nitrate anions and water molecules, held together through an extensive H-bonded system. The resulting 3D supramolecular architecture defines channels which are filled by lattice water molecules and disordered nitrate anions.

Two new copper(II) complexes have been synthesized and characterization, and they show extended structural dimensionality through supramolecular interactions. In this way the biimidazole present in these complexes nicely recognizes the dicarboxylate group.Figure optionsDownload as PowerPoint slide
