Sc3Co2Ge3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 11-coordinate geometry to four equivalent Co(1), two equivalent Ge(2), and five equivalent Ge(1) atoms. In the second Sc site, Sc(2) is bonded in a 9-coordinate geometry to four equivalent Co(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Co(1) is bonded in a 10-coordinate geometry to two equivalent Sc(2), four equivalent Sc(1), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to one Sc(2), five equivalent Sc(1), three equivalent Co(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Sc(2), four equivalent Sc(1), and two equivalent Co(1) atoms.
