The material described by Y2CoGe6 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(4), two equivalent Ge(5), and four equivalent Ge(6) atoms. In the second Y site, Y(2) is bonded in a 14-coordinate geometry to four equivalent Co(1), two equivalent Ge(1), two equivalent Ge(3), two equivalent Ge(6), and four equivalent Ge(5) atoms. Co(1) is bonded in a 9-coordinate geometry to four equivalent Y(2), one Ge(5), two equivalent Ge(1), and two equivalent Ge(3) atoms. There are six inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Y(2), two equivalent Co(1), one Ge(2), and four equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to two equivalent Y(1), one Ge(1), and four equivalent Ge(4) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Y(2), two equivalent Co(1), one Ge(4), and four equivalent Ge(1) atoms. In the fourth Ge site, Ge(4) is bonded in a 7-coordinate geometry to two equivalent Y(1), one Ge(3), and four equivalent Ge(2) atoms. In the fifth Ge site, Ge(5) is bonded in a 9-coordinate geometry to two equivalent Y(1), four equivalent Y(2), one Co(1), and two equivalent Ge(6) atoms. In the sixth Ge site, Ge(6) is bonded in a 8-coordinate geometry to two equivalent Y(2), four equivalent Y(1), and two equivalent Ge(5) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
