Abstract

New zinc(II) compounds with cyclobutane-1,1-dicarboxylic acid (H₂Cbdc) anions and calcium [CaZn(Cbdc)₂(H₂O)₃]_n (I) and barium [BaZn(Cbdc)₂(H₂O)₂]_n (II) cations were obtained. According to X-ray diffraction data (CIF files CCDC nos. 2055176 (I), 2055177 (II)), compounds I and II are coordination polymers in which zinc atoms are connected by bridging and chelating-bridging acid dianions to form 2D architectures with a square lattice topology. Alkaline earth metal atoms do not affect the dimensionality of compound packing.

Zn(II) 与环丁烷-1,1-二羧酸阴离子和钙钡阳离子配合物的合成与结构

摘要

具有环丁烷-1,1-二羧酸 (H ₂ Cbdc) 阴离子和钙 [CaZn(Cbdc) ₂ (H ₂ O) ₃ ] _n ( I ) 和钡 [BaZn(Cbdc) ₂ (H ) 的新型锌 (II) 化合物_{得到 2} O) ₂ ] _n ( II ) 阳离子。根据 X 射线衍射数据（CIF 文件 CCDC 编号 2055176（I）、2055177（II）），化合物I和II是配位聚合物，其中锌原子通过桥接和螯合桥接酸二价阴离子连接，形成具有方形晶格拓扑结构的二维结构。碱土金属原子不影响复合填料的维数。
