The ternary compound Tb_0.83Zn_0.14Sn_2.86 was observed for the first time. The X-ray single crystal method was used to determine the crystal structure. The new stannide crystallizes in a new structure type, which is a derivative of AuCu₃ (space group Pmm2, a = 4.332(3) Å, b = 4.427(3) Å, c = 5.479(4) Å). The structural relationship between Tb_0.83Zn_0.14Sn_2.86 and other structure types with small unit cells and close-packed structures is discussed.
