On the basis of the designed bifunctional 1,4-bis(imidazol-1-yl)terephthalic acid (H2BTA) ligand, a series of three-dimensional lanthanide coordination polymers, namely, [La2(BTA)1.5(ox)1.5(H2O)3] n (1), [Nd(BTA)(ox)0.5(H2O)] n (2), {[Ln(HBTA)(ox)(H2O)]·xH2O} n (Ln = Pr for 3 (x = 0), Sm for 4 (x = 0), Dy for 5 (x = 1.5), and Eu for 6 (x = 1)), and [Ln(BTA)(SO4)0.5(H2O)] n (Ln = Eu for 7, and Tb for 8) were obtained with the help of oxalate or sulfate ions. On the basis of the binuclear La2 secondary building unit (SBUs), the framework of 1 displays an unprecedented (3,3,4,9)-connected net with the point symbol of (411.55.614.75.8)2(42.5)2(43)2(44.62). While in complex 2, the binuclear Nd2 SBUs are connected by the BTA2– ligands to generate an interestingly (4,10)-connected (412.516.612.75)(46)2 net. Complexes 3–6 are isomorphism and show a 2-fold interpenetrated 4-connected (66)-dia net. Complexes 7 and 8 are isomorphism and show a novel (4,5)-connected (44.62)(44.66) net. Photoluminescence investigations show that 2 is a good near-infrared luminescent material, and 4 is a rarely reported single component white light emitting material. Complexes 6 and 7 show typically red emission, while complex 8 shows typically green emission, which can be used as a red or green emitting phosphor. Moreover, the luminescent lifetimes and quantum yields of the titled complexes were investigated. The magnetic susceptibility data of 2 indicated there are antiferromagnetic interactions between the NdIII ions.

“…S2). They also indicate characteristic adsorption bands, such as, a broad peak centered at 3400 cm À 1 can be observed, which is attributed to the O-H stretching vibration of the water molecules and the sharp bands in the ranges of 1690-1605 and 1440-1330 cm À 1 can be ascribed to asymmetric and symmetric stretching vibrations of carboxylic group, respectively [23]. No band in the region 1690-1730 cm À 1 , indicates complete deprotonation of the carboxylic groups [24], which is consistent with the result of the X-ray diffraction analysis.…”
