Synthesis, Reversible Phase Transition and Dielectric Properties of Molybdenum-Based Pyridines Organic-Inorganic Hybrid Crystalline Materials
The organic – inorganic hybrid crystalline material (C2H11N2)(4)[MoOBr4(H2O)](2)Br, (1) was synthesized by solvent evaporation method in the mixed solution of methanol, ethanol, water and hydrobromic acid using 4-dimethylaminopyridine and ammonium molybdate as raw materials. The crystal structure, thermal and electrical properties were characterized by infrared spectroscopy, single crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis and dielectric measurements and differential thermal analysis. Single crystal X-ray diffraction displayed one-dimensional chain and multi-dimensional hydrogen-bonding network structure through anions and cations forming a-ir stacking in space. When the temperature changed, the structural cavity deformation with molybdenum complex ion [MoOBr4(H2O)](-) as the vertex caused the hydrogen-bonding dihedral angles of tetramer [MoOBr4 (H2O)](2)Br-2 to occur obvious folding oscillation, which results in the distinct thermal energy with structural phase transition and reversible dielectric anomaly observed at around 238 K.
