The compound described by MnNiSb2 crystallizes in the trigonal P-3m1 space group. Mn(1) is bonded to two equivalent Ni(1) and six equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing MnNi2Sb6 hexagonal bipyramids. Ni(1) is bonded in a body-centered cubic geometry to two equivalent Mn(1) and six equivalent Sb(1) atoms. Sb(1) is bonded in a 6-coordinate geometry to three equivalent Mn(1) and three equivalent Ni(1) atoms. is represented by the CIF file [CIF]
