Abstract
A thallium cuprate, Tl5Ba3Sr5Cu3O19, whose structure can be derived by systematically shearing the ''1201'' structure has been synthesized f or the first time. It crystallizes in an orthorhombic cell with a = 3. 7536(2) Angstrom, b = 30.631(2) Angstrom, c = 9.219(1) Angstrom, and A -type symmetry. This new structure consists of ''1201'' ribbons parall el to (010) which are three CuO6 octahedra wide and are interconnected through ''Tl(2)A(2)O(4)'' ribbons whose cationic configuration is tha t of the rock salt structure. This phase can be considered to be the m = 3 member of a new series with the generic formulation (TlA(2)CuO(5) )(m) . Tl(2)A(2)O(4) with A = Ba,Sr. (C) 1997 Academic Press.
