Abstract

We report the synthesis and structural characterization of a new homologous series of lanthanum cuprates, with the formula La_4+4nCu_8+2nO_14+8n. The n = 2 and n = 3 members, La₂Cu₂O₅ and La₈Cu₇O₁₉, synthesized in the bulk, are stable in very narrow temperature ranges in air and oxygen. The n = 4 member was observed by electron microscopy. The crystal structure of La₂Cu₂O₅ consists of thin ribbons of La₂CuO₄ sandwiched between CuO planes of complex low dimensional geometry. The temperature-dependent magnetic susceptibilities of La₂Cu₂O₅ and La₈Cu₇O₁₉ are characteristic of low dimensional Heisenberg antiferromagnets with a low exchange coupling energy.
