Zabel, A. Poznyak, V. Pavlovskii] The crystal structure of Ca[Cr(Edda)(C2O4)]2·5H2O and Ba[Cr(Edda)(C2O4)]2·5H2O (H2Edda — ethylenediamine-N,N′-diacetic acid) was determined by X-ray diffraction analysis. The nearest environment of alkaline earth ions consists of the oxygen atoms of the neighboring [Cr(Edda)(C2O4)]− complex ions (five for Ca and four for Ba) and the water molecules that complete the coordination number to eight. Two atoms and two complex ions are linked into a ring; each Ca atom in the ring is bonded by the oxalate ion bridge to another anion. This results in a centrosymmetric hexanuclear supramolecular assembly. The atoms and the complex anions alternate to form an infinite chain, in which each Ba atom is additionally linked via the oxalate ion bridge with one anion.
