Abstract

Abstract : The inadvertently published phase transformation from MIL-53 to MIL-68 is merely a deformation of the MIL-53 structure upon DMF adsorption. Abstract : In a recently published communication ( CrystEngComm, 2018, 20, 402–406), Perea-Cachero et al. stated that the topologically isomeric metal–organic frameworks MIL-53(Al) and MIL-68(Al) could be reversibly transformed into each other. However, the suggested synthesis procedure for MIL-68 indeed resulted in MIL-53 with DMF entrapped inside of the pores. The collected PXRD pattern of MIL-53DMF was then inadvertently assigned to the MIL-68 structure.
