The compound described by Eu2Zn3Ge crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 12-coordinate geometry to two equivalent Zn(1), two equivalent Zn(2), four equivalent Zn(3), and four equivalent Ge(1) atoms. In the second Eu site, Eu(2) is bonded in a 12-coordinate geometry to two equivalent Zn(3), four equivalent Zn(1), four equivalent Zn(2), and two equivalent Ge(1) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 10-coordinate geometry to two equivalent Eu(1), four equivalent Eu(2), two equivalent Zn(2), and two equivalent Ge(1) atoms. In the second Zn site, Zn(2) is bonded in a 10-coordinate geometry to two equivalent Eu(1), four equivalent Eu(2), two equivalent Zn(1), and two equivalent Zn(3) atoms. In the third Zn site, Zn(3) is bonded in a 10-coordinate geometry to two equivalent Eu(2), four equivalent Eu(1), two equivalent Zn(2), and two equivalent Ge(1) atoms. Ge(1) is bonded in a 10-coordinate geometry to two equivalent Eu(2), four equivalent Eu(1), two equivalent Zn(1), and two equivalent Zn(3) atoms. is represented by the CIF file [CIF]
