The material structure described by BaSrGdBiO6 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pnnn space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms to form BaO12 cuboctahedra that share faces with four equivalent Gd(1)O6 octahedra and faces with four equivalent Bi(1)O6 octahedra. In the second Ba site, Ba(2) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(2) and four equivalent O(3) atoms. In the second Sr site, Sr(2) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. Gd(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form GdO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra and faces with two equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 18-24°. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with six equivalent Gd(1)O6 octahedra and faces with two equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 18-24°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Ba(1), one Ba(2), one Sr(2), one Gd(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Ba(1), one Ba(2), one Sr(1), one Gd(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Ba(1), one Sr(1), one Gd(1), and one Bi(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
