The material structure described by Zn2As is Cuprite structured and crystallizes in the cubic Pn-3m space group. Zn(1) is bonded in a linear geometry to two equivalent As(1) atoms. As(1) is bonded to four equivalent Zn(1) atoms to form corner-sharing AsZn4 tetrahedra. is represented by the CIF card [CIF]
