The crystal structures of the mixed valence compound Bi (IIII) 3 Bi (V) O 7 (1) and isotypic Bi (III) 3 Sb (V) O 7 (2) were determined ab initio from powder di4raction data. At room temperature, both structures crystallize in space group P1 (Z ؍ 2) with a ؍ 6.7253( 2), b ؍ 6.9950(2), c ؍ 7.7
The superconductivity-related self-energies of phonons in the high-To superconductor RBa2CuzOr\_~ (R = rare earth) have recently madepossible the determination of a ,Mac of the superconducting gapJ .The addition of impurities has the apparent effect of shifting this gap value to higher energies. We
