The material structure described by Ni5Sb2 crystallizes in the monoclinic C2/m space group. There are six inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to two equivalent Ni(1), two equivalent Ni(2), two equivalent Ni(3), two equivalent Ni(4), two equivalent Sb(1), and two equivalent Sb(2) atoms to form a mixture of distorted edge, corner, and face-sharing NiNi8Sb4 cuboctahedra. In the second Ni site, Ni(2) is bonded in a 11-coordinate geometry to two Ni(1,1); four Ni(4,4); two equivalent Sb(2); and three equivalent Sb(1) atoms. In the third Ni site, Ni(3) is bonded in a 10-coordinate geometry to two Ni(1,1); four Ni(4,4); two equivalent Sb(1); and two equivalent Sb(2) atoms. In the fourth Ni site, Ni(4) is bonded to one Ni(1); two equivalent Ni(2); two equivalent Ni(3); three Ni(4,4); two equivalent Sb(1); and two equivalent Sb(2) atoms to form a mixture of distorted edge, corner, and face-sharing NiNi8Sb4 cuboctahedra. In the fifth Ni site, Ni(4) is bonded to one Ni(1), two equivalent Ni(2), two equivalent Ni(3), three equivalent Ni(4), two equivalent Sb(1), and two equivalent Sb(2) atoms to form a mixture of distorted edge, corner, and face-sharing NiNi8Sb4 cuboctahedra. In the sixth Ni site, Ni(1) is bonded to two equivalent Ni(1), two equivalent Ni(2), two equivalent Ni(3), two equivalent Ni(4), two equivalent Sb(1), and two equivalent Sb(2) atoms to form a mixture of distorted edge, corner, and face-sharing NiNi8Sb4 cuboctahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 11-coordinate geometry to two Ni(1,1); two equivalent Ni(3); three equivalent Ni(2); and four Ni(4,4) atoms. In the second Sb site, Sb(2) is bonded in a 10-coordinate geometry to two Ni(1,1); two equivalent Ni(2); two equivalent Ni(3); and four Ni(4,4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
