An Interpenetrated Three-dimensional Framework Sodium Lanthanide Carboxylate Based onHo4(μ3-OH)48+Cluster

摘要

A novel sodium holmium carboxylate compound,namely Na 4 Ho 4 (μ 3-OH) 4 (1,4BDC) 6 ·6.25H 2 O (1,1,4-BDC=1,4-benzenedicarboxylate),has been solvothermally synthesized and structurally characterized.The structure features a two-fold interpenetrated three-dimensional open-framework constructed by the [Ho 4 (μ 3-OH) 4 ] 8+ clusters bridged by 1,4-BDC ligands.The Na + ions and lattice water molecules are located in the channels.The structure is further stabilized by hydrogen-bonding and π-π stacking interactions.The thermal stability of the compound has been investigated via thermogravimetric analysis.
