The material described by LaNiZn crystallizes in the hexagonal P-62m space group. La(1) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), and six equivalent Zn(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent La(1) and six equivalent Zn(1) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Zn(1) atoms. Zn(1) is bonded in a 12-coordinate geometry to six equivalent La(1), two equivalent Ni(1), two equivalent Ni(2), and two equivalent Zn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
