Abstract

Crystals of the 110 K superconductor TlBa₂Ca₂Cu₃O₉ have been grown and the structure refined from single-crystal X-ray diffraction data: a = 3.853(1), c = 15.913(4)Å, space group P4 mmm, R = 0.055, R_w = 0.057. The structure contains triple copper-oxygen sheets separated by Ca ions which show ∼5% Tl substitution. These units alternate with single TlO layers. The existence of correlated atomic displacements within the thallium-oxygen sheets is again suggested by a disordered TlO arrangement in the average structure. The triple CuO sheets in TlBa₂Ca₂Cu₃O₉ are stacked directly above each other, whereas in Tl₂Ba₂Ca₂Cu₃O₁₀, which contains double TlO sheets, alternate units are shifted by (a₁ + a₂) 2.
