Abstract

A novel compound [Mn(bip)2Cl2·4H2O] (1) [bip = 2-(4-bromophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline] has been synthesized by hydrothermal reactions and characterized by elemental analysis, thermogravimetric (TG) analysis, infrared spectrum (IR), XRD spectra (X-ray powder diffraction), and single-crystal X-ray diffraction. The title compound crystallizes in orthorhombic, space group pbcn with a = 1.4820, b = 0.8961, c = 2.8105 nm, β = 90°. Single-crystal X-ray diffraction reveals that compound 1 is zero-dimensional (0D) architecture, and the existence of hydrogen bonds and π-π interactions lead the 0D to 2D novel frameworks. Hydrogen bonds and π-π interactions are powerful interactions for directing supra-molecular architectures. TG analysis shows clear courses of weight loss, which corresponds to the decomposition of different ligands. The luminescent properties for the ligand bip and compound 1 are also discussed.
