The structure of molten FeCl[sub 3] at 320[sup degrees]C has been measured with neutron diffraction at the Intense Pulsed Neutron Source. Results indicate that melting in FeCl[sub 3]is accompanied by a change in local structure from the octahedral environment of the Fe[sup 3[plus]] in the solid to an Fe[sub 2]Cl[sub 6] molecular liquid. This behavior is similar to that observed in AlCl[sub 3] and in contrast to that of YCl[sub 3] where an octahedral coordination is preserved on melting. 3 figs, 1 tab, 12 refs.
