The crystal structure of DySr{sub 2}Cu{sub 2.7}Mo{sub 0.3}O{sub 7.2} and DySr{sub 2}Cu{sub 2.7}Cr{sub 0.3}O{sub 7.2} was solved by the X-ray powder diffraction method. The space group of DySr{sub 2}Cu{sub 2.7}Mo{sub 0.3}O{sub 7.2} (M{sub r} = 653.29) is P4/mmm, with lattice parameters a = 3.8262(1) {angstrom}, c = 11.5492(2) {angstrom}, and Z = 1. The space group of DySr{sub 2}Cu{sub 2.7}Cr{sub 0.3}O{sub 7.2} (M{sub r} = 640.11) is P4/mmm, with lattice parameters a = 3.8531(1) {angstrom}, c = 11.3804(2) {angstrom}, and Z = 1. Rietveld refinement results in the discrepancy factors R{sub B} = 7.93 and R{sub wp} = 3.76 for the Mo compound and R{sub B} = 9.76 and R{sub wp} = 4.07 for the Cr compound.
