The title compound, [Na2Zn(C10H4O8)(2)(H2O)(8)]. 2H(2)O, consists of six-co
ordinated Zn2+ and Na+ cations, aqua ligands, crystal water molecules and d
ihydrogen 1,2,4,5-benzenetetracarboxylate(2-) (H(2)btc) anions. The six-coo
rdinated zinc centers, which are situated at the inversion center, are link
ed into one-dimensional chains via six coordinated sodium ions in pairs and
extended further into a three-dimensional framework via hydrogen bonding.
