Materials Data on Nb6GePt by Materials Project

Nb6PtGe crystallizes in the cubic Pm-3 space group. The structure is three-dimensional. Nb is bonded in a 6-coordinate geometry to two equivalent Nb, two equivalent Pt, and two equivalent Ge atoms. Both Nb–Nb bond lengths are 2.60 Å. Both Nb–Pt bond lengths are 2.90 Å. Both Nb–Ge bond lengths are 2.90 Å. Pt is bonded to twelve equivalent Nb atoms to form PtNb12 cuboctahedra that share edges with six equivalent PtNb12 cuboctahedra and faces with eight equivalent GeNb12 cuboctahedra. Ge is bonded to twelve equivalent Nb atoms to form GeNb12 cuboctahedra that share edges with six equivalent GeNb12 cuboctahedra and faces with eight equivalent PtNb12 cuboctahedra.
