title: Translocation-coupled transmetalation at the origin of a dinuclear lead porphyrin complex: implication of a hanging-atop coordination mode.
abstract: Translocation of a lead cation from the N-core of a porphyrin to a hanging carboxylate group is coupled to a transmetalation process with a second lead cation, leading to a dinuclear species. A novel hanging-atop coordination mode is responsible for the dynamic and stereocontrolled binding of lead to the porphyrin core.
