Four novel lanthanide coordination polymers [Pr(mal)(OH)(bipy)·2H2O]n(1), {[Dy1(SBA)3(H2O)2][Dy2(SBA)3(H2O)2]·4H2O}n(2), {[Tb(OHnic)(Onic)(H2O)5·(OHnicH)]·H2O}n(3) and {[Sm(OHnic)(Onic)(H2O)5·(OHnicH)]·H2O}n(4) (Hmal=maleic acid, HSBA=4-sulfobenzoic acid, OHnicH=6-hydroxynicotinic acid and bipy=2,2′-bipyridine) have been synthesized and determined by single crystal X-ray diffraction. Complex 1 is a 1-D helical chain with seven-coordinated praseodymium centers. Complex 2 forms 1-D chain-like molecular structure containing two crystallographically unique dysprosium centers, the Dy1center is seven-coordinated while Dy2is eight-coordinated. The isomorphous complexes 3 and 4 exhibit an unprecedented 1-D chain-like polymeric structure through hydroxyl oxygen atoms of bridging Onic2−anions linking up the neighboring central ions, and there exist three types of 6-OHnicH ligands in the structural unit which is rare for lanthanide carboxylate complexes. The photophysical properties of these complexes were studied using ultraviolet absorption spectra, fluorescence excitation and emission spectra.
