The material structure described by Sc2(NbGe)3 crystallizes in the orthorhombic Amm2 space group. There are three inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 5-coordinate geometry to one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. In the second Sc site, Sc(2) is bonded in a 5-coordinate geometry to one Ge(1), two equivalent Ge(2), and two equivalent Ge(4) atoms. In the third Sc site, Sc(3) is bonded in a 5-coordinate geometry to one Ge(3), two equivalent Ge(1), and two equivalent Ge(4) atoms. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 5-coordinate geometry to one Ge(3), two equivalent Ge(2), and two equivalent Ge(4) atoms. In the second Nb site, Nb(2) is bonded in a 6-coordinate geometry to one Ge(1), one Ge(3), two equivalent Ge(2), and two equivalent Ge(4) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to one Sc(1), two equivalent Sc(2), two equivalent Sc(3), and four equivalent Nb(2) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Sc(1), two equivalent Sc(2), two equivalent Nb(1), and four equivalent Nb(2) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to one Sc(3), two equivalent Sc(1), two equivalent Nb(1), and four equivalent Nb(2) atoms.
