The crystal structure described by Tb3(MnC3)2 crystallizes in the hexagonal P6_3/m space group. Tb(1) is bonded in a 8-coordinate geometry to four equivalent C(1) and four equivalent C(2) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to six equivalent C(1) atoms to form face-sharing MnC6 octahedra. In the second Mn site, Mn(2) is bonded in a trigonal planar geometry to three 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 Tb(1), two equivalent Mn(1), and one C(2) atom. In the second C site, C(2) is bonded in a 6-coordinate geometry to four equivalent Tb(1), one Mn(2), and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
