Rare earth coordination polymers with zeolite topology constructed from 4-connected building units
A series of rare earth coordination polymers, M(BTC)(DMF)( DMSO) ( M = Tb ( 1), Ho ( 2), Er ( 3), Yb ( 4), Y( 5)), with zeolite ABW topology have been synthesized under mild conditions. They exhibit the same three-dimensional (3D) architecture and crystallize in monoclinic symmetry space group P2(1)/n. Their structures are built up from inorganic and organic 4-connected building units, whose vertex symbols are 4, 4, 6, 6, 6, 8. The building units link to each other to generate approximate 5 x 8 angstrom(2) channels along the [ 100] direction. The luminescent and magnetic properties of these compounds are investigated, and the results reveal that they could be anticipated to be potential antiferromagnetic and fluorescent materials.
