The crystal structure described by Dy2Mn17C3 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a trigonal planar geometry to two equivalent Mn(2), six equivalent Mn(4), and three equivalent C(1) atoms. In the second Dy site, Dy(2) is bonded in a trigonal planar geometry to three equivalent C(1) atoms. There are four inequivalent Mn sites. In the first Mn site, Mn(4) is bonded to two equivalent Dy(1), two equivalent Mn(2), four equivalent Mn(1), and four equivalent Mn(3) atoms to form distorted MnDy2Mn10 cuboctahedra that share corners with four equivalent Mn(4)Dy2Mn10 cuboctahedra, corners with two equivalent C(1)Dy2Mn4 octahedra, faces with six equivalent Mn(4)Dy2Mn10 cuboctahedra, and faces with four equivalent C(1)Dy2Mn4 octahedra. The corner-sharing octahedral tilt angles are 40°. In the second Mn site, Mn(1) is bonded in a single-bond geometry to two equivalent Mn(2), two equivalent Mn(4), and one C(1) atom. In the third Mn site, Mn(2) is bonded in a 14-coordinate geometry to one Dy(1), one Mn(2), three equivalent Mn(3), three equivalent Mn(4), and six equivalent Mn(1) atoms. In the fourth Mn site, Mn(3) is bonded in a single-bond geometry to one Mn(2), two equivalent Mn(4), and one C(1) atom. C(1) is bonded to one Dy(1), one Dy(2), two equivalent Mn(1), and two equivalent Mn(3) atoms to form CDy2Mn4 octahedra that share corners with two equivalent Mn(4)Dy2Mn10 cuboctahedra, corners with four equivalent C(1)Dy2Mn4 octahedra, and faces with four equivalent Mn(4)Dy2Mn10 cuboctahedra. The corner-sharing octahedral tilt angles are 60°. is represented by the CIF card [CIF]
