Crystal structures of barium bis(iminodiacetato)cobaltates(III): [Ba(H2O)6][Co(Ida)2]2 · H2O and Ba4(H2O)14][Co(Ida)2]5(ClO4)3 · 5.46H2O · 2CH3OH

The structures of the crystals of Ba₄[trans(N)-Co(Ida)₂]₃[cis-(N)-Co(Ida)₂]₂(ClO₄)₃ · 19.46H₂O · 2CH₃OH (I) and Ba[trans-(N)-Co(Ida)₂]₂ · 7H₂O (II) (H₂Ida 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. Original Russian Text ? M. Zabel, A.I. Poznyak, V.I.
