Solvent-induced single-crystal to single-crystal transformation of a Zn4O-containing doubly interpenetrated metal–organic framework with a pcu net

Abstract

Guest molecules in a metal–organic framework (MOF), [Zn₄O(CPMA)₃]·6DMF (DMF = N,N-dimethylformamide), with an interpenetrating pcu net were exchanged with benzene, n-hexane, and methanol in a single-crystal to single-crystal (SC–SC) manner, which involved the sliding motion of the interpenetrating network, as well as the dynamic movements of the molecular components, and was triggered by host–guest interactions.
