The compound described by Sm(NiGe)3 crystallizes in the tetragonal I4/mmm space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Ni(1), four equivalent Ni(2), four equivalent Ge(3), and four equivalent Ge(4) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 5-coordinate geometry to four equivalent Sm(1), one Ge(3), and four equivalent Ge(4) atoms. In the second Ni site, Ni(2) is bonded in a 6-coordinate geometry to two equivalent Sm(1), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a body-centered cubic geometry to eight equivalent Ni(2) atoms. In the second Ge site, Ge(2) is bonded in a body-centered cubic geometry to eight equivalent Ni(2) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Ni(1), and four equivalent Ni(2) atoms. In the fourth Ge site, Ge(4) is bonded in a 8-coordinate geometry to four equivalent Sm(1) and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
