Dy11(Mn2C3)6 crystallizes in the cubic I-43m space group. There are three inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 6-coordinate geometry to six equivalent C(2) atoms. In the second Dy site, Dy(2) is bonded in a 12-coordinate geometry to twelve equivalent Mn(1) atoms. In the third Dy site, Dy(3) is bonded in a 8-coordinate geometry to four equivalent C(1) and four equivalent C(2) atoms. Mn(1) is bonded in a distorted trigonal non-coplanar geometry to one Dy(2), one C(1), and two equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 7-coordinate geometry to four equivalent Dy(3), two equivalent Mn(1), and one C(1) atom. In the second C site, C(2) is bonded to two equivalent Dy(1), two equivalent Dy(3), and two equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing CDy4Mn2 octahedra. The corner-sharing octahedral tilt angles range from 3-70°.

There are three shorter (2.58 Å) and three longer (2.65 Å) Dy(1)-C(2) bond lengths. In the second Dy site, Dy(2) is bonded in a 12-coordinate geometry to twelve equivalent Mn(1) atoms. All Dy(2)-Mn(1) bond lengths are 2.88 Å. In the third Dy site, Dy(3) is bonded in a 8-coordinate geometry to four equivalent C(1) and four equivalent C(2) atoms. All Dy(3)-C(1) bond lengths are 2.63 Å. All Dy(3)-C(2) bond lengths are 2.49 Å. Mn(1) is bonded in a distorted trigonal non-coplanar geometry to one Dy(2), one C(1), and two equivalent C(2) atoms. The Mn(1)-C(1) bond length is 2.06 Å. Both Mn(1)-C(2) bond lengths are 1.86 Å. There are two inequivalent C sites.
