Influence of ligand field stabilization energy on the elastic properties of multiferroic MOFs with the perovskite architecture

Abstract

We report the mechanical properties of four isostructural metal–organic frameworks (MOFs) that adopt the ABX₃ perovskite topology: [(CH₃)₂NH₂]M(HCOO)₃, where M = divalent Mn, Co, Ni, and Zn. Their Young's moduli were measured via single-crystal nanoindentation. We show that the mechanical stability of such isostructural frameworks with octahedral coordination increases with greater ligand field stabilization energy (LFSE).
