The compound described by Dy2MnGe4 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 11-coordinate geometry to one Mn(1), two equivalent Ge(1), two equivalent Ge(3), two equivalent Ge(4), and four equivalent Ge(2) atoms. In the second Dy site, Dy(2) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(3), two equivalent Ge(4), and four equivalent Ge(1) atoms. Mn(1) is bonded in a 5-coordinate geometry to one Dy(1), one Ge(1), two equivalent Ge(3), and two equivalent Ge(4) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a distorted single-bond geometry to two equivalent Dy(1), four equivalent Dy(2), one Mn(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to two equivalent Dy(2), four equivalent Dy(1), and two equivalent Ge(1) atoms. In the third Ge site, Ge(3) is bonded in a 2-coordinate geometry to two equivalent Dy(1), two equivalent Dy(2), and two equivalent Mn(1) atoms. In the fourth Ge site, Ge(4) is bonded in a 2-coordinate geometry to two equivalent Dy(1), two equivalent Dy(2), and two equivalent Mn(1) atoms. is represented by the CIF card [CIF]
