TbRh3Si2 crystallizes in the hexagonal P6/mmm space group. Tb(1) is bonded in a 18-coordinate geometry to twelve equivalent Rh(1) and six equivalent Si(1) atoms. Rh(1) is bonded in a distorted square co-planar geometry to four equivalent Tb(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1) and six equivalent Rh(1) atoms.
