The crystal structure described by CuZnAs crystallizes in the orthorhombic Pna2_1 space group. Cu(1) is bonded in a 8-coordinate geometry to four equivalent Zn(1) and four equivalent As(1) atoms. Zn(1) is bonded in a 8-coordinate geometry to four equivalent Cu(1) and four equivalent As(1) atoms. As(1) is bonded in a body-centered cubic geometry to four equivalent Cu(1) and four equivalent Zn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
