Mn2CrSbO6 crystallizes in the monoclinic P2_1/c space group. Cr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CrO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-41°. Mn(1) is bonded in a 8-coordinate geometry to two equivalent O(3), three equivalent O(1), and three equivalent O(2) atoms. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-41°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Cr(1), three equivalent Mn(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Cr(1), three equivalent Mn(1), and one Sb(1) atom. In the third O site, O(3) is bonded to one Cr(1), two equivalent Mn(1), and one Sb(1) atom to form distorted corner-sharing OMn2CrSb trigonal pyramids.
