Solid-State Interconversions of Coordination Networks and Hydrogen-Bonded Salts

摘要

Much of modern materials science is underpinned by the ability to prepare crystalline phases of transition-metal compounds. Most such solids have been prepared by solution methods (e.g. for coordination framework materials[1] and salts of complex ions[2]) or by high-temperature (ceramic) methods for ionic solids (of monoatomic ions, oxides, etc.).[3] We report herein a range of modest-temperature, solid-state methods for the preparation of crystalline metal complexes in which the transformations between phases are achieved by chemical and mechanochemical procedures without the use of solutions. Such methods have been cited as providing green approaches to crystalline materials by minimizing solvent use, at least in this stage of the synthesis.
