Abstract

Two distinct one-dimensional (1) and two-dimensional (2) mixed-metal-organic polymers have been synthesized by using the "complex-as-ligand" strategy. The structure of 1 consists of isolated ladderlike Mn(II)(2)Cu(II)(2) chains separated from each other by neutral Mn(II)(2) dimers, whereas 2 possesses an overall corrugated layer structure built from additional coordinative interactions between adjacent Mn(II)(2)Cu(II)(2) ladders. Interestingly, 1 and 2 show overall ferri- and antiferromagnetic behavior, respectively, as a result of their distinct crystalline aggregation in the solid state.

摘要

两种不同的一维（1D）和二维（2D）混合金属有机聚合物已经通过“配合物作为配体”策略合成。1 的结构由彼此隔开的孤立梯形 Mn(II)(2)Cu(II)(2)链组成，而 2 具有由相邻 Mn(II)(2)Cu(II)(2)梯形之间额外的配位相互作用构建的整体波纹层结构。有趣的是，1 和 2 分别表现出整体亚铁磁和反铁磁行为，这是由于它们在固态中的不同晶体聚集。
