Sc6PdTe2 crystallizes in the orthorhombic Pnma space group. There are six inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 3-coordinate geometry to two equivalent Pd(1) and one Te(1) atom. In the second Sc site, Sc(2) is bonded to two equivalent Pd(1), one Te(2), and two equivalent Te(1) atoms to form distorted edge-sharing ScTe3Pd2 square pyramids. In the third Sc site, Sc(3) is bonded in a 4-coordinate geometry to one Pd(1), one Te(2), and three equivalent Te(1) atoms. In the fourth Sc site, Sc(4) is bonded in a 5-coordinate geometry to three equivalent Pd(1) and two equivalent Te(2) atoms. In the fifth Sc site, Sc(5) is bonded in a 4-coordinate geometry to two equivalent Te(1) and two equivalent Te(2) atoms. In the sixth Sc site, Sc(6) is bonded in a 2-coordinate geometry to one Pd(1) and one Te(2) atom. Pd(1) is bonded in a 9-coordinate geometry to one Sc(3), one Sc(6), two equivalent Sc(1), two equivalent Sc(2), and three equivalent Sc(4) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to one Sc(1), two equivalent Sc(2), two equivalent Sc(5), and three equivalent Sc(3) atoms. In the second Te site, Te(2) is bonded to one Sc(2), one Sc(3), one Sc(6), two equivalent Sc(4), and two equivalent Sc(5) atoms to form distorted edge-sharing TeSc7 pentagonal bipyramids.
