Materials Data on CuAsSe2 by Materials Project

Kristin Persson
CuAsSe2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Cu1+ is bonded to four equivalent Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent CuSe4 tetrahedra and corners with eight equivalent AsSe4 tetrahedra. All Cu–Se bond lengths are 2.43 Å. As3+ is bonded to four equivalent Se2- atoms to form AsSe4 tetrahedra that share corners with four equivalent AsSe4 tetrahedra and corners with eight equivalent...
