Abstract Heterometallic carboxylate complexes are of paramount interest in pure and applied coordination chemistry. Despite that plurality of such type compounds have been published to date, synthetic aspects of their chemistry often remain in the shadow of intriguing physical properties manifesting by these species. Present review summarizes reliable data on direct synthesis of low nuclearity molecular compounds as well as coordination polymers on their base with carboxylate-bridged {M2Mg} (M = Co2+, Ni2+, Cd2+), {M2Li2} (M = Co2+, Ni2+, Zn2+, VO2+), {M2Ln2} and {M2Ln} (M = Cu2+, Zn2+, Co2+) metal cores. Structural features and stabilization factors are considered and principal outcomes are confirmed by quantum-chemical calculations. Particular attention is paid to consideration of ligand-exchange reactions that allow controllable modification of heterometallic metal core under mild conditions giving diverse molecular complexes with modified ligand environment or Metal-Organic Frameworks with permanent porosity.

低核度异金属羧酸盐的形成和结构特征的一些方面

摘要 杂金属羧酸盐配合物在纯配位化学和应用配位化学中具有重要意义。尽管迄今为止已发表了多种此类化合物，但它们化学的合成方面通常仍处于这些物种所表现出的有趣物理特性的阴影中。本综述总结了直接合成低核分子化合物的可靠数据以及基于其与羧酸根桥接 {M2Mg}（M = Co2+、Ni2+、Cd2+）、{M2Li2}（M = Co2+、Ni2+、Zn2+、 VO2+)、{M2Ln2} 和 {M2Ln}（M = Cu2+、Zn2+、Co2+）金属核。考虑了结构特征和稳定因素，并通过量子化学计算确认了主要结果。
