摘要
用水热法合成了一种新的多价钼多酸配合物[Mo(Ⅳ)Mo2(Ⅴ)O7(Phen)],并用X射线衍射、元素分析、红外光谱、热重-差热、荧光光谱和磁化率等对其进行了表征。X射线衍射分析表明,配合物晶体属于单斜晶系,P2(1)/c空间群,由十二员环和八员环构成二维网状结构。配合物中强π-π堆积作用构筑成层状三维超分子,稳定了配合物晶体结构。荧光分析表明,配合物在397nm处有1个强发射峰。磁性测试结果表明,在0～300K温度范围内,配合物中自旋基态的Mo原子间仅存在反铁磁相互作用。此外,配合物还具有较高的热稳定性。
A novel organic-inorganic hybrid complex [Mo（Ⅳ）Mo2（Ⅴ）O7Phen] with multivalent molybdenum acid had been synthesized by hydrothermal reaction and characterized by single-crystal X-ray diffraction,elemental analyses,infrared spectroscopy,thermogravimetric-deferential thermal analysis,fluorescence spectroscopy and magnetic susceptibility.The complex belongs to monoclinic system with space group P 2（1）/c.The complex reveals the 2D network structures constructed by alternating twelve and eight membered ring,and further form 3D supramolecular structure by π-π stacking interaction which contributes to stabilize the network.Fluorescence analysis showed that complex has a strong emission peak in 397nm.Magnetic susceptibility results showed that the Mo atoms at the spin ground state only exist antiferromagnetic interaction in 0~300K.The complex also displays the high thermal stability.
