The structure described by MoMn2B4 crystallizes in the orthorhombic Immm space group. Mo(1) is bonded to four equivalent B(1) and eight equivalent B(2) atoms to form a mixture of distorted edge and face-sharing MoB12 cuboctahedra. Mn(1) is bonded in a 7-coordinate geometry to two equivalent B(2) and five equivalent B(1) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 7-coordinate geometry to two equivalent Mo(1), five equivalent Mn(1), and two equivalent B(2) atoms. In the second B site, B(2) is bonded in a 9-coordinate geometry to four equivalent Mo(1), two equivalent Mn(1), one B(2), and two equivalent B(1) atoms. is represented by the CIF file [CIF]
