Ba6Pr2Y(CuO2)12 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a distorted q6 geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.78–3.05 Å. In the second Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.78–3.08 Å. Pr4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Pr–O bond distances ranging from 2.49–2.51 Å. Y3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.41 Å) and four longer (2.43 Å) Y–O bond lengths. There are four inequivalent Cu+2.08+ sites. In the first Cu+2.08+ site, Cu+2.08+ is bonded to five O2- atoms to form corner-sharing CuO5 square pyramids. There are a spread of Cu–O bond distances ranging from 1.97–2.31 Å. In the second Cu+2.08+ site, Cu+2.08+ is bonded to five O2- atoms to form corner-sharing CuO5 square pyramids. There are a spread of Cu–O bond distances ranging from 1.97–2.32 Å. In the third Cu+2.08+ site, Cu+2.08+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.84–1.96 Å. In the fourth Cu+2.08+ site, Cu+2.08+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.85–1.96 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded to four Ba2+ and two Cu+2.08+ atoms to form a mixture of distorted edge and corner-sharing OBa4Cu2 octahedra. The corner-sharing octahedra tilt angles range from 11–12°. In the second O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Ba2+, two equivalent Pr4+, and two equivalent Cu+2.08+ atoms. In the third O2- site, O2- is bonded in a 6-coordinate geometry to two Ba2+, one Pr4+, one Y3+, and two Cu+2.08+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Ba2+, one Pr4+, one Y3+, and two Cu+2.08+ atoms. In the fifth O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Ba2+, two equivalent Pr4+, and two equivalent Cu+2.08+ atoms. In the sixth O2- site, O2- is bonded to four Ba2+ and two Cu+2.08+ atoms to form a mixture of distorted edge and corner-sharing OBa4Cu2 octahedra. The corner-sharing octahedra tilt angles range from 11–13°. In the seventh O2- site, O2- is bonded in a distorted T-shaped geometry to two Ba2+ and three Cu+2.08+ atoms. In the eighth O2- site, O2- is bonded in a distorted T-shaped geometry to two equivalent Ba2+ and three Cu+2.08+ atoms.
