The material described by DyMn2(Cr2Ge3)2 crystallizes in the orthorhombic Cmm2 space group. Dy(1) is bonded to four equivalent Mn(1), one Ge(3), one Ge(4), and six equivalent Ge(2) atoms to form a mixture of distorted face and edge-sharing DyMn4Ge8 hexagonal bipyramids. There are three inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 10-coordinate geometry to four equivalent Mn(1), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. In the second Cr site, Cr(2) is bonded in a 6-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(4) atoms. In the third Cr site, Cr(3) is bonded in a 6-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(4) atoms. Mn(1) is bonded in a 12-coordinate geometry to two equivalent Dy(1), two equivalent Cr(1), two equivalent Mn(1), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 6-coordinate geometry to one Cr(1), one Cr(3), two equivalent Cr(2), and two equivalent Mn(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Dy(1), one Cr(1), one Cr(3), two equivalent Cr(2), and two equivalent Mn(1) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Dy(1), two equivalent Cr(1), four equivalent Mn(1), and one Ge(4) atom. In the fourth Ge site, Ge(4) is bonded in a 8-coordinate geometry to one Dy(1), two equivalent Cr(3), four equivalent Cr(2), and one Ge(3) atom. is represented by the CIF card [CIF]
