La2Au is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent La sites. In the first La site, La(1) is bonded to four equivalent Au(1) atoms to form a mixture of distorted edge and corner-sharing LaAu4 tetrahedra. In the second La site, La(2) is bonded in a 3-coordinate geometry to three equivalent Au(1) atoms. Au(1) is bonded in a 7-coordinate geometry to three equivalent La(2) and four equivalent La(1) atoms.
La2Au is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent La sites. In the first La site, La(1) is bonded to four equivalent Au(1) atoms to form a mixture of distorted edge and corner-sharing LaAu4 tetrahedra. There are a spread of La(1)-Au(1) bond distances ranging from 3.04-3.23 Å. In the second La site, La(2) is bonded in a 3-coordinate geometry to three equivalent Au(1) atoms. There is one shorter (3.08 Å) and two longer (3.25 Å) La(2)-Au(1) bond lengths. Au(1) is bonded in a 7-coordinate geometry to three equivalent La(2) and four equivalent La(1) atoms.
