The crystal structure described by TbSe crystallizes in the hexagonal P6_3/mmc space group. Tb(1) is bonded to five equivalent Se(1) atoms to form a mixture of edge and corner-sharing TbSe5 trigonal bipyramids. Se(1) is bonded to five equivalent Tb(1) atoms to form a mixture of edge and corner-sharing SeTb5 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
