La4CuZn(RhO6)2 is Orthorhombic Perovskite-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.39–2.79 Å. In the second La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.39–2.78 Å. There are two inequivalent Rh4+ sites. In the first Rh4+ site, Rh4+ is bonded to six O2- atoms to form RhO6 octahedra that share corners with two equivalent CuO6 octahedra and corners with four equivalent ZnO6 octahedra. The corner-sharing octahedra tilt angles range from 29–30°. There are a spread of Rh–O bond distances ranging from 2.02–2.04 Å. In the second Rh4+ site, Rh4+ is bonded to six O2- atoms to form RhO6 octahedra that share corners with two equivalent ZnO6 octahedra and corners with four equivalent CuO6 octahedra. The corner-sharing octahedra tilt angles range from 29–30°. There are a spread of Rh–O bond distances ranging from 2.03–2.05 Å. Cu2+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with six RhO6 octahedra. The corner-sharing octahedra tilt angles range from 29–30°. There are a spread of Cu–O bond distances ranging from 2.06–2.09 Å. Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with six RhO6 octahedra. The corner-sharing octahedra tilt angles range from 29–30°. There are a spread of Zn–O bond distances ranging from 2.07–2.11 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to two La3+, one Rh4+, and one Zn2+ atom to form distorted corner-sharing OLa2ZnRh tetrahedra. In the second O2- site, O2- is bonded to two La3+, one Rh4+, and one Cu2+ atom to form distorted corner-sharing OLa2CuRh tetrahedra. In the third O2- site, O2- is bonded in a 5-coordinate geometry to three La3+, one Rh4+, and one Cu2+ atom. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to three La3+, one Rh4+, and one Zn2+ atom. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to three La3+, one Rh4+, and one Zn2+ atom. In the sixth O2- site, O2- is bonded in a 5-coordinate geometry to three La3+, one Rh4+, and one Cu2+ atom.
