The compound described by 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. is represented by the CIF card [CIF]
