Electron and powder diffraction were combined to elucidate the structure of the new coordination polymer [Sc-2(FcDC)(3)] based on 1,1'-ferrocenedicarboxylate (FcDC(2-)), denoted as CAU-50. Remarkably, three different conformers of the very same linker molecule are observed, two of which serve as connectors for the scandium cations while one conformer acts as capping agent.
