Photomechanical movement with a morphological deformation has been achieved in the crystalline state of a bipyridinium-based coordination polymer. The engine "heart" is the electron-deficient bipyridinium core sandwiched by electron-rich phenylcarboxylate components. The decorrelation of the CT state triggered by PET reaction in the engine "heart" promotes the occurrence of this mechanical movement.
