Dehydration‐Induced Conversion from a Single‐Chain Magnet into a Metamagnet in a Homometallic Nanoporous Metal–Organic Framework

Abstract

A change for the meta: On dehydration, a 3D homometallic porous organic–inorganic framework constructed from {Co3(OH)2} chains (see structure, pink Co, red O, blue N, gray C) undergoes a transition from being a single-chain magnet into a metamagnet. Apart from the loss of solvent water molecules, the dehydration leaves the framework structure largely unchanged.
