Crystal Structure of (+)490CDmer-Bis{bis(3-aminopropyl)aminecobalt(III)} Hexacyanocobaltate(III) Dihydrate, (+)490CDmer-[Co(dpt)2][Co(CN)6]·2H2O

The structure of optically active title compound was determined by X-ray diffraction. The absolute configuration is trans-δ-NH. A pair of two-fused six-membered rings is extended. The geometry of the octahedron is distorted by the presence of the six-membered chelate rings.
