    Abstract:
    The title complex is isomorphous with α- [Ni(OH2) 6] [SO4] with space group either P412 12 or P43212, a = 6.953(4), c = 18.33(2) Å, and Z = 4. Intensity data have been collected by equi-inclination Weissenberg methods and the 433 independent reflections judged visually. The resulting structure has been solved by the heavy-atom method and refined by full-matrix least squares to a final R value of 0.107. Although doped to 38 mol % with CoII, the structure shows no demonstrable difference from that expected for the pure complex. From the absolute configuration determined by the Bijvoet method, and circular-dichroism measurements made on the same crystal, it is found that space group P41212 correlates with a negative rotational strength in the major ligand-field bands of [Co(OH2)6]2+.
