摘要:
Reactions in water between lanthanide chlorides and the di-sodium salt of 1,2-phenylenediacetic acid, Na-2(o-pda), lead to two families of coordination polymers with respective chemical formulae [La-2(o-pda)(3)(H2O)(4),4H(2)O](infinity) (1) and [Ln(2)(o-pda)(3)(H2O)(2),2H(2)O](infinity) (2) for Ln = Ce-Nd, Sm-Lu and Y. Compound 1 crystallises in the monoclinic system, space group C2/c (n degrees 15), with a = 28.195(5) angstrom, b = 12.2305(3) angstrom, c = 8.7607(1) angstrom, beta = 98.835(1) angstrom and Z = 4. Its crystal structure and thermal properties are described. Compounds of family 2 are isostructural to a previously reported crystal structure. Luminescence properties of Eu-and Tb-based compounds have been studied. (C) 2017 Elsevier B. V. All rights reserved.
