The compound described by Sr2Mn3(BiO)2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 4-coordinate geometry to four equivalent Bi(1) and four equivalent O(1) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a square co-planar geometry to two equivalent Bi(1) and four equivalent O(1) atoms. In the second Mn site, Mn(2) is bonded in a 4-coordinate geometry to four equivalent Bi(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Mn(1), and four equivalent Mn(2) atoms. O(1) is bonded to four equivalent Sr(1) and two equivalent Mn(1) atoms to form a mixture of edge, face, and corner-sharing OSr4Mn2 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
