The material described by Yb2(ZnGe)3 crystallizes in the monoclinic C2/m space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 14-coordinate geometry to one Zn(3), two equivalent Zn(2), three equivalent Zn(1), one Ge(3), three equivalent Ge(2), and four equivalent Ge(1) atoms. In the second Yb site, Yb(2) is bonded in a 6-coordinate geometry to two equivalent Zn(1), one Ge(2), two equivalent Ge(1), and three equivalent Ge(3) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 10-coordinate geometry to two equivalent Yb(2), three equivalent Yb(1), one Zn(3), one Ge(1), and three equivalent Ge(2) atoms. In the second Zn site, Zn(2) is bonded in a 4-coordinate geometry to two equivalent Yb(1), one Ge(1), one Ge(2), and two equivalent Ge(3) atoms. In the third Zn site, Zn(3) is bonded in a 4-coordinate geometry to one Yb(1), one Zn(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Yb(2), four equivalent Yb(1), one Zn(1), one Zn(2), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Yb(2), three equivalent Yb(1), one Zn(2), two equivalent Zn(3), and three equivalent Zn(1) atoms. In the third Ge site, Ge(3) is bonded in a 7-coordinate geometry to one Yb(1), three equivalent Yb(2), two equivalent Zn(2), and two equivalent Zn(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
