[LiNa(N5)2(H2O)4]·H2O: 一种含螺旋链的新型双金属五唑骨架


过去一个世纪以来, 探索合成含有五唑阴离子(cyclo-\(\rm{N}_5^-\))的聚氮化合物吸引了科学家们的极大兴趣. 本论文报道了一例基于异质双 金属的五唑骨架, [LiNa(N5)2(H2O)4]·H2O(1), 并对其结构和热性质进行了表征. 单晶X射线衍射表明化合物1具有三维超分子结构, 其中相邻的{Li(H2O)2(N5)5}三聚体之间通过O–H⋯N氢键作用形成左手型和右手型螺旋链结构. 化合物1在室温条件下具有良好的热稳定性, 五唑环在106.1°C开始分解. 本研究对于探索五唑阴离子的配位化学以及相关聚氮材料提供了新思路.
