NdLa3(CuO4)2 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.32–2.75 Å. There are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 2-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.31–2.76 Å. In the second La3+ site, La3+ is bonded in a 2-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.31–2.76 Å. In the third 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 2.32–2.76 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to six O2- atoms to form corner-sharing CuO6 octahedra. The corner-sharing octahedra tilt angles range from 9–10°. There are a spread of Cu–O bond distances ranging from 1.92–2.50 Å. In the second Cu2+ site, Cu2+ is bonded to six O2- atoms to form corner-sharing CuO6 octahedra. The corner-sharing octahedra tilt angles range from 9–10°. There are a spread of Cu–O bond distances ranging from 1.92–2.46 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to one Nd3+, three La3+, and two Cu2+ atoms to form distorted face-sharing OLa3NdCu2 octahedra. In the second O2- site, O2- is bonded in a 6-coordinate geometry to one Nd3+, three La3+, and two Cu2+ atoms. In the third O2- site, O2- is bonded in a 5-coordinate geometry to one Nd3+, three La3+, and one Cu2+ atom. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Nd3+, two La3+, and one Cu2+ atom. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to one Nd3+, three La3+, and one Cu2+ atom. In the sixth O2- site, O2- is bonded in a 5-coordinate geometry to four La3+ and one Cu2+ atom.
