(4, 4)- and (6, 3)-2-D luminescent lanthanide(III) metal-organic frameworks constructed from tetrafluorosuccinate and 1,10-phenanthroline

Two new coordination polymers [Eu2(TFSA)3(phen)2]n (1) and [Tb2(TFSA)3(phen)4(H2O)2]n (2) (TFSA = tetrafluorosuccinate, phen = 1,10-phenanthroline) have been synthesized and structurally characterized. The 1 has a 2-D grid-like network structure with (4, 4) topology and the 2 has a 2-D honeycomb-like network structure with (6, 3) topology. The two complexes exhibit strong photoluminescence of the Eu(III) for 1 and Tb(III) for 2, respectively.
