The compound described by Sr5In2Bi6 crystallizes in the orthorhombic Pbam space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to two equivalent Bi(1) and four equivalent Bi(2) atoms to form a mixture of corner and edge-sharing SrBi6 octahedra. The corner-sharing octahedral tilt angles range from 27-43°. In the second Sr site, Sr(2) is bonded to two equivalent Bi(1) and four equivalent Bi(3) atoms to form a mixture of distorted corner, edge, and face-sharing SrBi6 octahedra. The corner-sharing octahedral tilt angles range from 27-53°. In the third Sr site, Sr(3) is bonded in a 9-coordinate geometry to two equivalent In(1), one Bi(1), two equivalent Bi(3), and four equivalent Bi(2) atoms. In(1) is bonded in a 4-coordinate geometry to two equivalent Sr(3), one Bi(2), one Bi(3), and two equivalent Bi(1) atoms. There are three inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to one Sr(1), one Sr(3), two equivalent Sr(2), and two equivalent In(1) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to two equivalent Sr(1), four equivalent Sr(3), one In(1), and one Bi(2) atom. In the third Bi site, Bi(3) is bonded to two equivalent Sr(3), four equivalent Sr(2), and one In(1) atom to form a mixture of distorted corner, edge, and face-sharing BiSr6In pentagonal bipyramids. is represented by the CIF card [CIF]
