Ba2Mn3(SbO)2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a 4-coordinate geometry to four equivalent Sb(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 Sb(1) and four equivalent O(1) atoms. In the second Mn site, Mn(2) is bonded to four equivalent Sb(1) atoms to form a mixture of distorted edge and corner-sharing MnSb4 tetrahedra. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Ba(1), one Mn(1), and four equivalent Mn(2) atoms. O(1) is bonded to four equivalent Ba(1) and two equivalent Mn(1) atoms to form a mixture of edge, face, and corner-sharing OBa4Mn2 octahedra. The corner-sharing octahedra are not tilted.
