The crystal structure of the new Tb13ZnSn13 compound (space group I4/mmm, = 11.599(2) Å, = 27.247(5) Å) was determined by X-ray single crystal diffraction. The composition was confirmed by EDX analysis. The compound crystallizes in its own structure type, which can be built from fragments that are related to the U3Si2, CsCl, PtHg2, α-Po, and InBi structure types.
