The compound described by Sr2MnZn2(AsO)2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 4-coordinate geometry to four equivalent As(1) and four equivalent O(1) atoms. Mn(1) is bonded in a square co-planar geometry to two equivalent As(1) and four equivalent O(1) atoms. Zn(1) is bonded to four equivalent As(1) atoms to form a mixture of edge and corner-sharing ZnAs4 tetrahedra. As(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Mn(1), and four equivalent Zn(1) 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 Crystallographic Information File (CIF) [CIF]
