The Materials Project

K2VAgSe4 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. There are a spread of K–Se bond distances ranging from 3.42–3.85 Å. V5+ is bonded to four equivalent Se2- atoms to form VSe4 tetrahedra that share edges with two equivalent AgSe4 tetrahedra. All V–Se bond lengths are 2.32 Å. Ag1+ is bonded to four equivalent Se2- atoms to form AgSe4 tetrahedra that share edges with two equivalent VSe4 tetrahedra. All Ag–Se bond lengths are 2.64 Å. Se2- is bonded in a 1-coordinate geometry to four equivalent K1+, one V5+, and one Ag1+ atom.
