Ba2PrSnO6 crystallizes in the trigonal R-3 space group. Ba(1) is bonded to twelve equivalent O(1) atoms to form distorted BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with six equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Pr(1)O6 octahedra, and faces with four equivalent Sn(1)O6 octahedra. Pr(1) is bonded to six equivalent O(1) atoms to form PrO6 octahedra that share corners with six equivalent Sn(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 8°. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 8°. O(1) is bonded in a 2-coordinate geometry to four equivalent Ba(1), one Pr(1), and one Sn(1) atom.
