Coordination polymers (CPs) may undergo structural transformations as a result of external stimuli (e.g., heat, light, or mechanochemical force). Structural transformations are accompanied by the movement of atoms or molecules and involve significant rearrangement of CP structures including rotation, bending, swinging, sliding, shrinking, or swelling. Lead(II) CPs display interesting structural features, varying properties and can be employed to investigate such transformations. In the present review, we focus on solid-state reactions of lead(II) CPs from a crystallographic point of view. Structural transformations of lead(II) CPs have been reported by our research group along with relevant examples from the literature. We also demonstrate that lead(II) CPs can create diverse structures with interesting features through such transformations. All the coordination networks have been determined by single-crystal X-ray diffraction before and after the structural transformations.
