Abstract

A study by means of electron microscopy and electron diffraction of synthetic digenite reveals the existence of a series of closely related structures with basic spacings 2a_o, 3a_o, 4a_o, 5a_o and 6a_o, where a_o is the (111) spacing of the cubic close packed sulphur sublattice. In all these structures copper atoms occupy tetrahedral interstices in a cubic close packed matrix of sulphur atoms. By means of high resolution microscopy non-rational spacings are shown to be the result of a mixture of spacings. It is shown that the particular set of systematic extinctions in the diffraction pattern discussed in previous papers, is related to a particular state of disorder and does not imply the presence of twinning.
