Local structure and dynamics in metal-imidazolate frameworks

DOI

This proposal aims to study local structure and dynamics in two metal-organic frameworks (MOFs): namely, zinc imidazolate and 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 silica analogues. Zn(IM)2 and Co(IM)2 are dense tetrahedral frameworks whose dynamical behaviour we expect to be strongly influenced by rigid-body-type vibrations of the imidazole molecule and the [ZnN4] and [CoN4] coordination polyhedra. We will characterise local structure and dynamics in these two materials by performing total scattering experiments on GEM at a range of temperatures. RMC analysis of these data will allow us to extract quantitative dynamical information that will be of high importance to the MOF community. We will also characterise the low-T magnetic structure of Co(IM)2.
