Abstract

The crystal structure of covellite has been studied under pressure up to 33 kbar based on single-crystal diffraction intensities collected with a four-circle diffractometer. The contraction of the unit cell takes place in such a way that the axial ratio c/a is kept nearly constant, the cell volume at 1 bar being reduced by about 5% at 33 kbar. With the contraction of the Cu – S bonds the sulfur-sulfur bond of the S2 group shows a trend of lengthening in a way similar to the relation between S – S and M – S bonds in the compounds MS2 (M = Cu, Ni, Co, Fe) having the pyrite structure type.
