• Two compounds have been synthesized and characterized.
• Weak interactions provide additional assembly forces. The fluorescence spectrum of the complexes are investigated.
In our efforts to tune the structures of compounds by selection of polycarboxylic acid ligands and N-heterocyclic ligands, two novel unreported compounds [Mn(cipt)(m-BDC)·H2O]n (1) and [Zn(mip)(NDC)]n (2) were obtained by hydrothermal reaction, where cipt = 2-(3-chlorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline, m-BDC = isophthalic acid, mip = 2-(3-methoxyphenyl)-1H-imidazo[4,5-f][1,10]phenanthroline, and NDC = naphthalene-1,4-dicarboxylic acid. All compounds have been characterized by IR, elemental analyses, single crystal X-ray diffraction, and thermogravimetric analysis (TGA). Structural analyses show that compounds 1 and 2 possess mononuclear structures and exhibit 1D zigzag chain structure. The intermolecular O–H⋯O and N–H⋯O interactions extend the compounds into 2D sheet networks. There are H-bonds and π–π interactions in the title compounds. Furthermore, the solid-state fluorescence spectrum of compounds 1 and 2 were also investigated.
The reaction of Mn(SO4)2·H2O, ZnCl2 with N-heterocyclic ligands and poly-carboxylate ligands yielded two novel coordination polymers. All compounds were characterized by elemental analysis, FT-IR, thermogravimetric analysis and X-ray crystallography. Furthermore, we studied the solid-state and solvent fluorescence spectrum, as well as the ligands.Figure optionsDownload as PowerPoint slide
