Mn8O10Cl3 crystallizes in the cubic Fm-3m space group. There are four inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in an octahedral geometry to six equivalent Cl(1) atoms. In the second Mn site, Mn(2) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. In the third Mn site, Mn(3) is bonded in an octahedral geometry to six equivalent O(2) atoms. In the fourth Mn site, Mn(4) is bonded in a distorted square co-planar geometry to two equivalent O(1), two equivalent O(2), and two equivalent Cl(1) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal planar geometry to one Mn(3) and two equivalent Mn(4) atoms. In the second O site, O(1) is bonded to one Mn(2) and three equivalent Mn(4) atoms to form a mixture of distorted corner and edge-sharing OMn4 tetrahedra. Cl(1) is bonded in a 5-coordinate geometry to one Mn(1) and four equivalent Mn(4) atoms.
