Two
series of eight polycarboxylate lanthanide coordination complexes,
namely, [Ln(cpia)(H2O)2]·4H2O {Ln = Ce (1), Nd (2), and Sm (3)} and [Ln(cpia)(H2O)n]2·2H2O {Ln = Eu (4), Gd (5), Tb (6), Er (7),
and Lu (8), n = 5 in 4–7; n = 4 in 8} {H3cpia = N-[4-(carboxymethoxy)phenyl]iminodiacetic
acid}, have been synthesized by self-assembly and characterized by
IR, thermogravimetric analysis, and X-ray crystallography. Complexes 1–3 are isomorphic featuring two-dimensional
double layer structures, while the isomorphic complexes 4–8 exhibit [2 + 2] rectangle metallomacrocycle
structures. Further, photoluminescence (PL) spectra of complexes 2, 4, and 6 show the strong characteristic
luminescence of Eu(III), Tb(III), and Nd(III) ions, respectively,
suggesting that cpia3– is able to efficiently sensitize
the luminescence of lanthanide ions.
