Abstract
Seven Ln(III) coordination polymers, namely [Ln(PODA)(FA)(H2O)]n [Ln=La(1), Ce(2), Pr(3), Nd(4), Eu(5)] and [Ln(PODA)1.5(phen)]n [Ln=La(6), Pr(7)] (H2PODA=1,3-phenylenebis(oxy)diacetic acid, HFA=formic acid, phen=1,10-phenanthroline) have been synthesized under hydrothermal conditions and characterized by IR spectroscopy, elemental analysis, single crystal X-ray crystallography, UV–Vis spectroscopy and powder X-ray diffraction analysis (PXRD). Structural analysis reveals that 1–5 are isostructural and exhibit 3-D frameworks with a (32.42.52)2(38.420.524.614) topology, which comprise single- and quadruple-strand helical chains; while 6 and 7 show similar layer structures with a (44.62) topology, however, they only consist of one kind of single-strand helical chain. In addition, the thermal stabilities of complexes 3 and 7 and the luminescent properties of complex 5 have been briefly investigated.
