The material described by Yb11(Mn2C3)6 crystallizes in the cubic I-43m space group. There are three inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 6-coordinate geometry to six equivalent C(2) atoms. In the second Yb site, Yb(2) is bonded in a 8-coordinate geometry to four equivalent C(1) and four equivalent C(2) atoms. In the third Yb site, Yb(3) is bonded in a 12-coordinate geometry to twelve equivalent Mn(1) atoms. Mn(1) is bonded in a distorted trigonal non-coplanar geometry to one Yb(3), 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 Yb(2), two equivalent Mn(1), and one C(1) atom. In the second C site, C(2) is bonded to two equivalent Yb(1), two equivalent Yb(2), and two equivalent Mn(1) atoms to form a mixture of distorted edge and corner-sharing CYb4Mn2 octahedra. The corner-sharing octahedral tilt angles range from 1-71°. is represented by the CIF file [CIF]
