The compound described by Ni5Ge3 crystallizes in the monoclinic C2/c space group. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 12-coordinate geometry to one Ni(1), one Ni(2), four equivalent Ni(3), two equivalent Ge(1), and four equivalent Ge(2) atoms. In the second Ni site, Ni(2) is bonded to two equivalent Ni(1), four equivalent Ni(3), two equivalent Ge(1), and four equivalent Ge(2) atoms to form a mixture of edge and corner-sharing NiNi6Ge6 cuboctahedra. In the third Ni site, Ni(3) is bonded in a 11-coordinate geometry to two equivalent Ni(2), four equivalent Ni(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to two equivalent Ni(2), four equivalent Ni(1), and four equivalent Ni(3) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Ni(2), three equivalent Ni(3), and four equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
