A Novel Metal−Organic Framework with the Diamondoid Topology Constructed from Pentanuclear Zinc−Carboxylate Clusters

A new 3D MOF, [Zn5(μ3-O)2(bpdc)4(DMF)2(EtOH)2]·3(DMF)·3(EtOH)·5(H2O) (1) (bpdc = 4,4‘-biphenyldicarboxylate,
DMF = N,N-dimethylformamide and EtOH = ethanol), has been synthesized under mild conditions. X-ray crystallography reveals that
polymer 1 consists of a 3D framework with an expanded diamondoid topology constructed from double 4-connected pentanuclear SBUs
linked by rigid bpdc ligands. For an unusual pentanuclear framework, polymer 1 shows the favorable CH3OH adsorption behavior and
good optoelectronic effect, which will facilitate the exploration of new types of multifunctional materials.
