The structure described by MnNiAl2 crystallizes in the tetragonal P4/mmm space group. Mn(1) is bonded in a 8-coordinate geometry to eight equivalent Al(1) atoms. Ni(1) is bonded in a body-centered cubic geometry to eight equivalent Al(1) atoms. Al(1) is bonded in a 8-coordinate geometry to four equivalent Mn(1) and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
