Abstract

Two novel coordination polymers, [Zn(dpc)(bmix)0.5]n (1), [Pb(dpc)(bmix)0.5]n (2), [dpc = dipicolinate, bmix = 1,4-bis(2-methylimidazole-1-ylmethyl)benzene], were hydrothermally synthesized and characterized by elemental analyses, IR spectroscopy, TGA, and X-ray single crystal diffraction. In both complexes, the dipicolinate and bmix ligands act as spacers to link metal ions to give a 2D corrugated (6,3) network of 1 and a 3D microporous framework of 2, respectively. The difference in the architectures is due to a diverging coordination mode of the carboxylate function. Furthermore, solid state fluorescence properties of the two complexes were investigated at room temperature.
