The structures of the crystals of Ba-4[trans(N)-Co(Ida)(2)](3)[cis-(N)-Co(Ida)(2)](2)(ClO4)(3) center dot 19.46H(2)O center dot 2CH(3)OH (I) and Ba[trans-(N)-Co(Ida)(2)](2) center dot 7H(2)O (II) (H(2)Ida is iminodiacetic acid) were determin by X-ray diffraction. The crystals of I containing two geometric isomers of the complex anions [Co(Ida)(2)](-) were obtained by a slow cooling of a hot solution, which contained initially only the cis-isomer. One Ba atom in I interacts with the trans-complex and with two cis-complexes to give a three-dimensional framework in crystal I. The positive charge of the last framework is compensated by one more trans-complex and by the perchlorate ions, one of which acts as a bidentate ligand with respect to the Ba atom. The crystals of II are built of the chains with the alternating Ba atoms and the trans-(N)-[Co(Ida)(2)](-) anions. The other anions of the same structure are each "suspended" to the Ba atoms of the chain.
