摘要：

The structure of TlCu7Se4 (synthetic crookesite) has been refined from X-ray powder data using the Rietveld technique. The compound is isostructural with NH4Cu7S4 and TlCu7S4, although successful refinements from two independent data sets (both with RF = 6.4%) occurred in I4 m rather than I4 previously suggested for this structure type. Positional parameters of natural crookesite were refined from somewhat inferior single-crystal data to RF = 8.5%. © 1991.
