NbGeSb is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Nb(1) is bonded in a 9-coordinate geometry to four equivalent Ge(1) and five equivalent Sb(1) atoms. Ge(1) is bonded in a 8-coordinate geometry to four equivalent Nb(1) and four equivalent Ge(1) atoms. Sb(1) is bonded in a 5-coordinate geometry to five equivalent Nb(1) atoms.
NbGeSb is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Nb(1) is bonded in a 9-coordinate geometry to four equivalent Ge(1) and five equivalent Sb(1) atoms. All Nb(1)-Ge(1) bond lengths are 2.75 Å. There are four shorter (2.89 Å) and one longer (3.04 Å) Nb(1)-Sb(1) bond length. Ge(1) is bonded in a 8-coordinate geometry to four equivalent Nb(1) and four equivalent Ge(1) atoms. All Ge(1)-Ge(1) bond lengths are 2.64 Å. Sb(1) is bonded in a 5-coordinate geometry to five equivalent Nb(1) atoms.
