The structure described by Pt5Ni4Ge is Tetraauricupride-derived structured and crystallizes in the tetragonal P4/mmm space group. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to four equivalent Ni(1) and four equivalent Ge(1) atoms to form distorted PtNi4Ge4 cuboctahedra that share corners with four equivalent Pt(1)Ni4Ge4 cuboctahedra, corners with eight equivalent Ge(1)Ge4Pt8 cuboctahedra, edges with four equivalent Ge(1)Ge4Pt8 cuboctahedra, edges with eight equivalent Pt(1)Ni4Ge4 cuboctahedra, and faces with five equivalent Pt(1)Ni4Ge4 cuboctahedra. In the second Pt site, Pt(2) is bonded in a distorted body-centered cubic geometry to four equivalent Ni(1) and four equivalent Ni(2) atoms. In the third Pt site, Pt(3) is bonded to eight equivalent Ni(2) atoms to form a mixture of distorted edge and face-sharing PtNi8 cuboctahedra. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to four equivalent Pt(1) and four equivalent Pt(2) atoms to form distorted NiPt8 cuboctahedra that share corners with four equivalent Ni(2)Pt8 cuboctahedra, corners with four equivalent Ge(1)Ge4Pt8 cuboctahedra, edges with four equivalent Ni(1)Pt8 cuboctahedra, edges with four equivalent Ni(2)Pt8 cuboctahedra, edges with four equivalent Ge(1)Ge4Pt8 cuboctahedra,  a faceface with one Ni(2)Pt8 cuboctahedra,  a faceface with one Ge(1)Ge4Pt8 cuboctahedra, and faces with four equivalent Ni(1)Pt8 cuboctahedra. In the second Ni site, Ni(2) is bonded to four equivalent Pt(2) and four equivalent Pt(3) atoms to form a mixture of distorted edge, corner, and face-sharing NiPt8 cuboctahedra. Ge(1) is bonded to eight equivalent Pt(1) and four equivalent Ge(1) atoms to form distorted GeGe4Pt8 cuboctahedra that share corners with four equivalent Ge(1)Ge4Pt8 cuboctahedra, corners with eight equivalent Ni(1)Pt8 cuboctahedra, corners with sixteen equivalent Pt(1)Ni4Ge4 cuboctahedra, edges with eight equivalent Pt(1)Ni4Ge4 cuboctahedra, edges with eight equivalent Ni(1)Pt8 cuboctahedra, faces with two equivalent Ni(1)Pt8 cuboctahedra, and faces with eight equivalent Ge(1)Ge4Pt8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
