The crystal structure described by La3(PtZn)4 crystallizes in the orthorhombic Immm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded to two equivalent Pt(1) and four equivalent Pt(2) atoms to form edge-sharing LaPt6 octahedra. In the second La site, La(2) is bonded in a 12-coordinate geometry to two equivalent Pt(1), four equivalent Pt(2), and six equivalent Zn(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to one La(1), two equivalent La(2), and six equivalent Zn(1) atoms. In the second Pt site, Pt(2) is bonded in a 8-coordinate geometry to two equivalent La(1), four equivalent La(2), and two equivalent Zn(1) atoms. Zn(1) is bonded in a 4-coordinate geometry to three equivalent La(2), one Pt(2), and three equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
