The material structure described by Ba5Mn5O14 crystallizes in the orthorhombic Ama2 space group. There are three inequivalent Ba sites.

The corner-sharing octahedral tilt angles range from 8-10°. In the second Ba site, Ba(2) is bonded in a 11-coordinate geometry to one O(1), one O(3), one O(5), one O(6), one O(8), two equivalent O(2), two equivalent O(4), and two equivalent O(7) atoms.
