Sr2PrGeO6 is Orthorhombic Perovskite-derived structured and crystallizes in the cubic Pn-3 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to twelve equivalent O(1) atoms to form SrO12 cuboctahedra that share faces with four equivalent Pr(1)O6 octahedra and faces with four equivalent Ge(1)O6 octahedra. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Pr(1) is bonded to six equivalent O(1) atoms to form PrO6 octahedra that share corners with six equivalent Ge(1)O6 octahedra and faces with two equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 21°. Ge(1) is bonded to six equivalent O(1) atoms to form GeO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra and faces with two equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 21°. O(1) is bonded in a 5-coordinate geometry to one Sr(1), two equivalent Sr(2), one Pr(1), and one Ge(1) atom.
