The structure described by La2ZnAs4 crystallizes in the tetragonal I-4m2 space group. La(1) is bonded in a 10-coordinate geometry to two equivalent Zn(1), four equivalent As(1), and four equivalent As(2) atoms. Zn(1) is bonded to four equivalent La(1) and four equivalent As(2) atoms to form distorted edge-sharing ZnLa4As4 tetrahedra. There are two inequivalent As sites. In the first As site, As(2) is bonded in a 6-coordinate geometry to four equivalent La(1) and two equivalent Zn(1) atoms. In the second As site, As(1) is bonded in a distorted body-centered cubic geometry to four equivalent La(1) and four equivalent As(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
