Hydrothermal syntheses and structures of lanthanide coordination polymers with 5-aminoisophthalate and 1,10-phenthroline

摘要

Two new lanthanide coordination polymers, [Ln_2(APA) _2(HAPA)_2(phen)_2] _n [Ln = Pr (1), Eu (2); H_2APA = 5-aminoisophthalic acid, phen = 1,10-Phenanthroline] have been synthesized by hydrothermal method, and characterized by single crystal X-ray diffraction, elemental analysis and IR spectra. Crystallographic data show that complexes 1 and 2 both crystallize in a triclinic system, space group $$ Par{1} $$. The titled compounds own 2-D herringbone structures which are further constructed to form 3-D supramolecular structures by N-H???O and O-H???O hydrogen bondings. The thermogravimetric analyses were carried out to examine the thermal stability of the title complexes. And the photoluminescence property of 2 was investigated.
