    Structural Analysis of Some Molten Materials by X-ray Diffraction Part 5.—LiCl, PbCL and their Mixtures
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1978, 74 (07), 1978) Ohno, Hideo; Yoroki, Mitsugu; Furukawa, Kazuo; Takagi, Yoshiki; Nakamura, Tetsuro
    The molten structure of PbCl2, LiCl and their mixtures were examined by X-ray diffraction analysis. In molten Pbcl2, each Pb atom is surrounded by about eight Cl atoms at a distance of 2.92 Å, which is near to the sum of the ionic radii of Pb2+ and Cl–. It is expected that only very few rigid complex anions will be present in molten PbCl2. The results of X-ray diffraction analysis in molten PbCl2 are consistent with those of Raman spectroscopy. The average Pb–Pb interaction in the molten state should be intermediate between a b.c.c. and an s.c. arrangement and the s.c. arrangement takes precedence with increasing LiCl concentration.

    Structural Analysis of Some Molten Materials by X-ray Diffraction: Part 3.—MnCl2
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1978, 74 (04), 1978) Ohno, Hideo; Furukawa, Kazuo; Tanemoto, Kei; Tagaki, Yoshiki; Nakamura, Tetsuro
    The structure of molten MnCl2 has been examined by consideration of the radial distribution function. The nearest Mn-Cl distance is 2.51 A and the coordination number of manganese is 4.0. An f.c.c. structural model with loosely distributed Cl atoms was proposed on the basis of tetrahedral coordination of Cl atoms around each Mn atom.
