Local structure, dynamics and magnetism of the phases of cobalt imidazolate


This proposal concerns the metal-organic framework (MOF), cobalt imidazolate. Imidazole (im) is a small, flat organic molecule that forms slightly bent metal-im-metal linkages, analogues to the Si-O-Si linkages in the silica phases. Co(im)2 forms a number of tetrahedral frameworks, including an amorphous phase, whose dynamical behaviour we expect to be strongly influenced by rigid-body-type vibrations of the imidazole molecule and the [CoN4] coordination polyhedra. We will characterise local structure, dynamics and magnetic structure in this material by performing temperature-dependent total scattering experiments analysed using RMC modelling. The resultant information will be of high importance to the MOF community. This proposal follows from RB910399, where we observed the ZIF-4 to amor-ZIF to ZIF-zni phase behaviour in the related non-magnetic Zn(im)2 for the first time.
