Abstract

The charge distribution in PbX (X = S, Se, Te) has been studied by accurate intensity measurement and difference synthesis. The cell edges are a 5.934(1) for PbS, 6.128(1) for PbSe and 6.462(1) A for PbTe (all cubic, space group Fm3m). No overlap electron density was observed corresponding with covalent Pb-X bonds: the bonding electrons may be delocalized like free electrons in metals. The thermal vibration parameters of Pb were greater than those of the X atoms and anharmonic thermal vibration of Pb was detected on the difference maps.-J.E.C.
