摘要：

A new Ce(III) coordination polymer, {[Ce(stp)(bipy)(H2O)]center dot H2O) (1) is afforded via the reaction of trivalent cerium nitrate [Ce(NO3)(3).6H(2)O], 2-sulfoterephthalic acid monosodium salt Na(H(2)stp), 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 Xray 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. (C) 2017 Elsevier B.V. All rights reserved.
