Nano/Microporous Materials: Transition Metal Cyanides

Abstract

Transition metal–cyanide clusters, in which the cyanide anion acts as a bridging ligand, exhibit a rich variety of shapes and sizes, from simple squares to high‐nuclearity cubes and octahedra. Clusters may be homometallic or heterometallic, and a significant fraction of the transition metals are represented among these materials. Magnetic coupling in these clusters is widespread owing to the proximity of the metals and short length of the bridging cyanide. This review examines the structures and magnetic properties of the major types of transition metal–cyanide cluster materials.
