Mn3Ni9Ga4 is Tungsten-derived structured and crystallizes in the cubic Pm-3m space group. Mn(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Ni(1) and two equivalent Ga(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 8-coordinate geometry to three equivalent Mn(1), one Ni(2), one Ga(1), and three equivalent Ga(2) atoms. In the second Ni site, Ni(2) is bonded in a distorted body-centered cubic geometry to eight equivalent Ni(1) and six equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted body-centered cubic geometry to six equivalent Mn(1) and eight equivalent Ni(1) atoms. In the second Ga site, Ga(2) is bonded in a distorted body-centered cubic geometry to two equivalent Ni(2) and eight equivalent Ni(1) atoms.
