The structure described by CuAgSe is Matlockite structured and crystallizes in the orthorhombic Pmmn space group. Ag(1) is bonded in a 9-coordinate geometry to four equivalent Cu(1) and five equivalent Se(1) atoms. Cu(1) is bonded to four equivalent Ag(1) and four equivalent Se(1) atoms to form a mixture of distorted face and edge-sharing CuAg4Se4 tetrahedra. Se(1) is bonded in a 9-coordinate geometry to five equivalent Ag(1) and four equivalent Cu(1) atoms. is represented by the CIF file [CIF]
