Abstract

A new Ce(III) coordination polymer, [Ce(stp)(bipy)(H2O)]·H2On (1) is afforded via the reaction of trivalent cerium nitrate [Ce(NO3)3·6H2O], 2-sulfoterephthalic acid monosodium salt Na(H2stp), and 4,4′-bipyridine (bipy). Based upon the versatile coordination modes of the stp ligand as linker and bipy as connector, the aforementioned compound is arranged in a 2-D network, as evidenced by single-crystal X-ray diffraction technique. In 1, the central Ce atom possesses on a distorted tricapped trigonal-prismatic coordination environment. The EPR measurement reveals that there exhibits a weak antiferromagnetic coupling between paramagnetic Ce3+ ions. The encapsulation of the Ce(III) CP disposes a moderate luminescent activity. Thermal analysis is also carried out to check the water loss of the molecule which is in accordance with the structural evidence.
