The Morris group has synthesized and studied a new class of metal organic frameworks (MOFs) termed VPI-100-M. The MOFs incorporate a tetra-azamacrocyle and have been shown to drive both the utilization of CO<sub>2</sub> and the reduction of CO<sub>2</sub>. Herein, a detailed mechanistic study of the interactions between the MOF and substrates of interest is presented. The implications of these results on the mechanism of catalytic action is discussed and placed in the context of the MOF catalytic field. Interestingly, we found that in these zirconium-based MOFs that the node plays a minor role in the observed chemistry in contrast to many of the other examples in the field. This was attributed mainly due to steric bulk of the reactive catalytic centers. Thus, steric bulk may be a method to control the reactivity within and stability of MOFs toward a variety of catalytic transformations that also include the degradation of chemical warfare agents.
