Notes:
The coordination of water molecules about the Dy3+ ion in a 2.38 m DyCl3 in D2O solution has been determined by neutron scattering. The information was obtained using samples that were identical except for the isotopic species of the Dy3+ ions. The experiment yields the distribution of the deuterium and oxygen atoms in the first hydration shell. Each Dy3+ ion is surrounded by 7.4±0.5 water molecules. The dysprosium–oxygen separation is 2.37 A(ring) and the dysprosium–deuterium separation is 3.04 A(ring). The cation–water molecule orientation is closer to planar than that which has generally been observed in other aqueous solutions.
