Description
YBa2Cu3-0.06(1)O7-0.18(2), Mr = 659.5, orthorhombic, Pmmm, a=3.836(1), b = 3.883(1), c = 11.686(1) A, V = 174.07 A3, Z = 1, F(000) = 290.82, Dx = 6.36 Mg m-3, λ(Mo Kα) = 0.7107 A, μ = 28.48 mm-1, T = 295 K, R = 0.0495, wR = 0.0341 for 1342 unique diffractometer data [F2 > 1σ(F2)] up to (sin θ)/λ = 1.15 A-1, only 3 reflections had intensities smaller than 1 standard deviation. The crystal of dimensions 0.1 x 0.075 x 0.025 mm was apparently untwinned. Precise positional and thermal parameters were obtained. The exact formula is YBa2Cu2Cu0.94O4O1.84O0.83O0.15. (orig.)
