New ternary antimonide Dy{sub 3}Cu{sub 20+x}Sb{sub 11-x} (x{approx}2) was synthesized and its crystal structure was determined by direct methods from X-ray powder diffraction data (diffractometer DRON-3M, CuK{alpha}-radiation, R{sub I}=6.99%,R{sub p}=12.27%,R{sub wp}=11.55%). The compound crystallizes with the own cubic structure type: space group F4-bar 3m, Pearson code cF272, a=16.6150(2)A,Z=8. The structure of the Dy{sub 3}Cu{sub 20}Sb{sub 11-x} (x{approx}2) can be obtained from the structure type BaHg{sub 11} by doubling of the lattice parameter and subtraction of 16 atoms. The studied structure was compared with the structures of known compounds, which crystallize in the same space group with similar cell parameters.
