Observation of three different linker conformers in a scandium ferrocenedicarboxylate coordination polymer†
Abstract
Electron and powder diffraction were combined to elucidate the structure of the new coordination polymer [Sc2(FcDC)3] based on 1,1′-ferrocenedicarboxylate (FcDC2−), 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.
