Synthesis, structural, and luminescence of two coordination polymers

摘要

A organic compound and its lanthanide coordination polymer with chemical formulae HL1, {[La(L-1)(3)(H2O)(2)] center dot 2H(2)O center dot 2,2'-Bipy} (I), (HL1 = 3-(4-hydroxyphenyl)propanoic acid, 2,2'-Bipy = 2,2'-bipyridine) have been synthesized and structurally characterized. Organic compound HL1 shows 1D supramolecular chain constructing from intermolecular hydrogen-bonded interaction. Complex II has 1D infinite chain with a [La(L-1)(3)] (n) dimeric repeat unit with lanthanide in a nine-coordinate environment. Furthermore, the luminescent properties of the two compounds were discussed in detail (CIF files CCDC nos. 1045032 (HL1), 1045033 (I)).
