Structural and luminescence characterizations of lanthanide-based coordination polymers involving naphthalene-1,4,5,8-tetra-carboxylate as ligand

Résumé

Reactions in water between lanthanide ions and the sodium salt ofnaphthalene-1,4,5,8- tetra-carboxylic acid lead tothree famil ies ofcoordination polymers asmicrocrystalline powders and/or single crystals. Their respective chemical formulae are {[Ln(ntc)(H2O)5][Ln(H2O)10]1/3,3H2O}1 with Ln =Ce,GdorEu (family 1),[NaYb(ntc)(H2O)6,4H2O]1 (family 2),and [Ln 2(ntc)1.5(H2O)11,9H2O]1 with Ln =Dy-Erand Y (family 3).The crys tal structure offamily 1has been solved onthe basis ofthe Ce-containing comp ound. This compound crystallizes inthe monoclinic system,space group C2/c (n 15) with a = 32.2307(6)Å, b = 6.6168(1)Å, c = 22.4244(4)Å, b = 91.814(1) , V = 4779.92(14)Å3 and Z = 4.The only compound that constitutes family 2crystallizes inthe monoclinic system,space group C2/c (n 15) with a = 6.3396(1)Å, b = 18.0440(2)Å, c = 19.6225 (2)Å, b = 95.451(1) , V = 2234.50(5)Å3 and Z = 4.The crystal structure of family 3has been solved onthe basis ofthe Er-containing comp ound.This comp ounds crys- tallizes in the monoclinic system,space group P21/a (n 14) with a = 22.0121(2)Å, b = 6.6973(1)Å, c = 26.4380(4)Å, b = 108.4 469(4) , V = 3697.27(9)Å3 and Z = 4.Its crystal structure can bedescribed as a co-crystalliza tion ofthe two others.Surprisingly,all these compounds present low-dim ensionality while lanthanide-containi ngcoordination polymers involving similar ligands,such asbenzene-1,2, 4,5-tetracarboxylate, show most often high dimensionality.The thermal behavior and the photo- luminescence properties ofthe compounds that belong tothe third family have been studied.
