The coordination by water (hydration) of the Cl/sup -/ ion in a 2.85 m NdCl/sub 3/ in D/sub 2/O solution has been determined by neutron diffraction. The information was obtained by using samples that were identical except for the isotopic species of the Cl/sup -/ ions. The experiment yields the distribution of the deuterium and oxygen atoms in the first hydration shell. Each Cl/sup -/ ion is surrounded by 3.9 water molecules, the chlorine-deuterium separation being 2.29 A. This hydration number is low compared with those of other chloride solutions, in which the value is close to 6. This is the first time that the hydration of Cl/sup -/ ions in the presence of trivalent cations has been investigated by the isotope method.
