Probing post-synthetic metallation in metal–organic frameworks: insights from X-ray crystallography

Abstract

For post-synthetic metallation (PSMet) of a metal–organic framework (MOF, [Mn₃(L₂)(L′)] = 1) we show a solvent dependency for the form of the metallated product. PSMet of 1 with MnCl₂ in ethanol leads to a single metal entity per coordinating site while acetonitrile yields a remarkably complex multiply metallated product; thus, determining the extent of metallation requires an intimate understanding of the chemistry occurring in the MOF pores.
