Crystals with uncommon composition NaBa6[Co(Edta)](4)(ClO4)(9) - 30H(2)O (Edta(4-) is ethylenedi= aminetetraacetic acid anion) were obtained with the following unit cell parameters: a = 14.8513(9) angstrom, b = 26.2361(15) angstrom, c =15.1789(9) angstrom, alpha = 91.661(7)degrees, (beta = 113.035(7)degrees, gamma= 89.897(7)degrees, space group P1. Each complex anion [Co(Edta)]- is bonded through the carboxyl O atoms to five Ba atoms to give three-dimensional framework in a crystal. One perchlorate ion forms Ba-O-Cl-O-Ba bridge between the Ba atoms; four ClO4- ions are isolated, while the remaining four ions act as monodentate ligands at the Ba atoms. The water molecules (25 in sum) complete the coordination sphere of the Ba atoms to eight-, nine-, or ten-vertex polyhedron. Four water molecules are in the closest surrounding of the Na atom, one H2O molecule is isolated.
