Crystals of Ba Na ethylenediaminetetraacetatocobaltate(III) perchlorate, NaBa2[Co(Edta)](2)(ClO4)(3)center dot 9H(2)O, contain two crystallographically nonequivalent Ba2+ cations and two complex cations [Co(Edta)](Edta(4-) is ethylenediaminetetraacetic acid anion), the latter anions showing opposite chirality. The nearest surrounding of the Ba2+ ions involves three water molecules (including two bridging water molecules), six O atoms of four complexes [Co(Edta)]- and the perchlorate O atom. Tetrameric fragments Ba-2(H2O)(4)[Co(Edta)](2)(ClO4)(2) are united through the Ba-O bonds into layers with the Ba atoms in the middle of the layers and the perchlorate ions and complex anions at the periphery; in the latter anions, noncoordinated O atom of one of the R-metallocycles is directed outside. The Na atom of the Na(H2O)(ClO4) group located between the layers is bonded to these O atoms of the neighboring layers.
