High-temperature superconductivity was observed in the system (M/sub x/Y/sub 1/..sqrt../sub x/)Ba/sub 2/Cu/sub 3/O/sub 6.5+//sub delta/) where M = Ga, Bi, or Fe. Ga and Fe substituted for Y reduce the orthorhombic distortion in the YBa/sub 2/Cu/sub 3/O/sub 6.5+//sub delta/ tetragonal lattice. The changes in transition temperature at zero resistance are not related to gradual changes in the orthorhombic distortion. High T/sub c/ superconductivity (T/sub c//sup R//sup //sup = //sup 0/ = 86 K) can be maintained in an undistorted tetragonal lattice. Bi substituted for Y does not substantially change the lattice parameters of the YBa/sub 2/Cu/sub 3/O/sub 6.5-//sub delta/ compound
