Mn2AlB2 crystallizes in the orthorhombic Cmmm space group. Mn(1) is bonded in a 6-coordinate geometry to six equivalent B(1) atoms. Al(1) is bonded in a distorted linear geometry to two equivalent B(1) atoms. B(1) is bonded in a 9-coordinate geometry to six equivalent Mn(1), one Al(1), and two equivalent B(1) atoms.
Mn2AlB2 crystallizes in the orthorhombic Cmmm space group. Mn(1) is bonded in a 6-coordinate geometry to six equivalent B(1) atoms. There are four shorter (2.11 Å) and two longer (2.16 Å) Mn(1)-B(1) bond lengths. Al(1) is bonded in a distorted linear geometry to two equivalent B(1) atoms. Both Al(1)-B(1) bond lengths are 2.26 Å. B(1) is bonded in a 9-coordinate geometry to six equivalent Mn(1), one Al(1), and two equivalent B(1) atoms. Both B(1)-B(1) bond lengths are 1.74 Å.
