Engineering of octacyanometalate-based coordination networks towards functionality

摘要

The design and construction of new supramolecular coordination compounds based on octacyanometalate [M(CN)_8]~(3-/4-) (M = Mo and W) building blocks of potential utility as functional materials has received considerable attention over the recent years. The research in this field has resulted in the cyano-bridged polynuclear octacyanometalate-based molecules and polymeric coordination networks which behave like molecular magnets and photo-induced magnetic materials. This article surveys the superstructural complexity of some coordination frameworks built by multidirectional non-rigid octacyanometalate anions as linkers in self-assembly with convergent Mn(Ⅱ,Ⅲ), Co(Ⅲ), Cu(Ⅱ) and Pt(Ⅱ) complexes with polyamine, diimine and Schiff-base blocking ligands. The role of intermolecular directional forces in propagation of M-CN-M′ linkages into the architectures of various dimensionalities and topologies is pointed out. The network topologies are outlined and the structure/property relationship is discussed.
