As part of an ongoing effort to understand the underlying physics of MOFs, we propose to study the local structure and dynamics in two quartz-like systems: indium deuterium terephthalate and zinc nicotinamide. By focussing on MOFs with direct SiO2 analogues it becomes possible to quantify which aspects of their behaviour can be well understood in terms of the dynamics of "traditional" frameworks, and which aspects are unique to the MOF family. We have chosen systems that exhibit negative thermal expansion behaviour, and which contain a range of "supramolecular" interactions ¿ pi-pi stacking and hydrogen bonding ¿ whose effect on the dynamical behaviour of these materials we aim to quantify. We will use GEM to collect total scattering data for a range of temperatures and use these data to produce reverse Monte Carlo (RMC) configurations, on which our analysis will be based.
