一维化合物(C_2H_8N)[Hg_2Cl_5]的晶体结构与介电性质的研究（英文）

Crystal Structure and Dielectric Property of a One-Dimentional Compound(C_2H_8N)[Hg_2Cl_5]

二甲基胺盐酸盐与氯化汞在水溶液中的反应,生产了一种有机无机杂化化合物(C2H8N)[Hg2Cl5](1)。单晶衍射分析证明化合物1的阴离子为沿b轴方向由氯桥构成的一维阴离子链,每1个汞都与4个氯离子配位。在处于80～298 K温度区间中,化合物1的介电没有出现介电异常的现象,这表明没有相变的发生。

Reaction of dimethylammonium chloride with mercuric chloride in aqueous solution yielded one novel organic-inorganic hybrid compound （C2H8N）[HgzCl5] （1）. X-ray structure determination reveals that complex 1 shows a one-dimensional chloride-bridged [Hg2Cl5]n anionic chain structure along the b axis. Each Hg（II） ion is coordinated with four chloride ions. Temperature-dependent dielectric constant of 1 shows no distinct anomalies, suggesting no phase transition occurred in the measured temperature range 80-298 K. CCDC： 880350.
