Accessing mixed cluster rare-earth MOFs with reduced connectivity via linker expansion and desymmetrization: co-assembly of 6-c and 10-c hexanuclear clusters in RE-stc-MOF-1

Abstract

MOFs based on hexanuclear rare-earth (RE) clusters with reduced connectivity (<12) are rare. The co-assembly of RE clusters with distinct reduced connectivity provides access to novel structures. We report a new family of MOFs denoted as RE-stc-MOF-1, displaying a unique (3,3,3,3,6,10)-connected network, based on 6-c and 10-c RE hexanuclear clusters.
