摘要：

Oxides of the type TlSr2Cu1-xMxO5 (M = Fe, 0.5 ≤ x ≤ 0.75; M = Co, 0.3 ≤ x ≤ 0.5) have been synthesized and characterized for the first time. These oxides were monophasic and crystallized in a primitive tetragonal structure (c-parameters ∼9.0 Å. Lattice parameters vary systematically with x. All the oxides show semiconducting behavior. Neutron powder diffraction study on TlSr2Cu0.4Fe0.6O5-δ shows structural features similar to those of other 121 oxides, but has comparatively less disorder in the TlO plane and has axially compressed Cu FeO6 octahedra. © 1991.
