The material described by TbMn3 crystallizes in the hexagonal P6_3/mmc space group. Tb(1) is bonded to twelve Mn(1,1) atoms to form a mixture of corner and face-sharing TbMn12 cuboctahedra. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 12-coordinate geometry to four equivalent Tb(1) and eight Mn(1,1) atoms. In the second Mn site, Mn(1) is bonded in a 12-coordinate geometry to four equivalent Tb(1) and eight equivalent Mn(1) atoms. is represented by the CIF file [CIF]
