The crystal structure of covellite CuS under high pressure up to 33 kbar

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.
