The compound described by La2PtNi crystallizes in the orthorhombic Amm2 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 7-coordinate geometry to four equivalent Pt(1) and three equivalent Ni(1) atoms. In the second La site, La(2) is bonded in a 7-coordinate geometry to three equivalent Pt(1) and four equivalent Ni(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to three equivalent La(2), four equivalent La(1), and two equivalent Ni(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent La(1), four equivalent La(2), and two equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
