Ni5Zn4Ge is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a body-centered cubic geometry to four equivalent Zn(1) and four equivalent Ge(1) atoms. In the second Ni site, Ni(2) is bonded in a body-centered cubic geometry to four equivalent Zn(1) and four equivalent Zn(2) atoms. In the third Ni site, Ni(3) is bonded in a body-centered cubic geometry to eight equivalent Zn(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ni(1) and four equivalent Ni(2) atoms. In the second Zn site, Zn(2) is bonded in a body-centered cubic geometry to four equivalent Ni(2) and four equivalent Ni(3) atoms. Ge(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Ni(1) atoms.
