The crystal structure described by Mg2Pr2(BiO4)3Bi crystallizes in the cubic Pn-3 space group. The structure consists of two 7440-69-9 atoms inside a Mg2Pr2(BiO4)3 framework. In the Mg2Pr2(BiO4)3 framework, Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 39°. Pr(1) is bonded to six equivalent O(1) atoms to form PrO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 39°. Bi(2) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded in a distorted trigonal planar geometry to one Mg(1), one Pr(1), and one Bi(2) atom. is represented by the CIF card [CIF]
