Reactions in water between lanthanide chlorides and the di-sodium salt of 1,2-phenylenediacetic acid,
Na2(o-pda), lead to two families of coordination polymers with respective chemical formulae [La2(o pda)3(H2O)4,4H2O]1 (1) and [Ln2(o-pda)3(H2O)2,2H2O]1 (2) for Ln = Ce-Nd, Sm-Lu and Y. Compound 1
crystallises in the monoclinic system, space group C2/c (n 15), with a = 28.195(5) Å, b = 12.2305(3) Å,
c = 8.7607(1) Å, b = 98.835(1) and Z = 4. Its crystal structure and thermal properties are described.
Compounds of family 2 are isostructural to a previously reported crystal structure. Luminescence prop erties of Eu- and Tb-based compounds have been studied.
