The compound described by LaZnSn crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 12-coordinate geometry to six equivalent Zn(1) and six equivalent Sn(1) atoms. In the second La site, La(2) is bonded to six equivalent Sn(1) atoms to form distorted edge-sharing LaSn6 octahedra. Zn(1) is bonded in a 6-coordinate geometry to three equivalent La(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a 9-coordinate geometry to three equivalent La(1), three equivalent La(2), and three equivalent Zn(1) atoms. is represented by the CIF file [CIF]
