A series of alkylidyne-capped trinuclear molybdenum (IV) clusters have been synthesized and characterized using spectroscopic techniques. The inductive ability of the alkyl group on the bridging carboxylates was varied to analyze the affect on rates of terminal ligand substitution. The rate data for the first substitution step was collected using variable-temperature <sup>1</sup>H NMR. Trends in reactivity are supported using Hammett constants. The reactivity trends, which are dictated by structure, can be used to develop a model for catalyst selection.
