Interest in metal-metal bonding in polymetallic complexes has undergone a recent resurgence due to potential application towards small molecule transformations with green energy implications. In particular, complexes containing both a late transition metal and early transition metal have been the focus of extensive study, under the presumption that pairing highly differentiated metal centers may significantly alter the fundamental chemistry of the resulting molecules. To further understand and develop multimetallic chemistry, new ligand scaffolds are necessary to support multiple metal sites. This research focuses on the use of a new 2-diphenylphosphinopyrrolide ligand to synthesize group 4, 5, and 6 based metalloligands. Successful treatment with a late transition metal results in both bi- and trimetallic complexes. The fundamental structure, bonding, and reactivity of these complexes will be discussed as well as potential strategies for the synthesis of other polymetallic complexes.
