Abstract
Abstract
The reactions of Zn(NO3)2 · 6H2O/CuCl2 · 2H2O and 1,4-bis(1-imidazolyl)benzene (bib)/1,4-bis(1-imidazol-1-ylmethyl)benzene (biyb), carried out under hydrothermal conditions, produced two new coordination polymers [Zn(bib)(HCOO)2 · H2O] (1) and [Cu(biyb)Cl2] (2), respectively, which were characterized by elemental analysis, infrared spectroscopy, thermogravimetric analyses, and single-crystal X-ray diffraction. In complex 1, the ZnII centers are bridged by bib ligands to form a chain, where the adjacent chains are condensed by strong intermolecular O–H · · · O hydrogen-bonding and aromatic π-π stacking interactions to generate a 3D supramolecular structure. In 2, the CuII centers are bridged by biyb ligands to form, again, chains through C–H · · · Cl hydrogen bonds, and these adjacent chains with different orientations are joined to generate a 3D supramolecular structure.
