title: Polyanions in molten KPb-a paradox explained?
abstract: We have created new models of the structure of liquid KPb at 873, 1473 and 1873 K. These are used to illustrate specific points concerning the 'existence' of Pb(4)(4-) polyanions or 'Zintl' ions. We conclude that such groupings exist but are only transient, probably with a timescale of the order of 1 ps. All of the existing experimental data are consistent with such a model.
