Single-crystal growth of a new sodium molybdenum bronze Na_(0.86)Mo_5O_(14)

摘要

A single crystal of sodium molybdenum bronze with the composition Nan^MosOn has been grown successfully in our search for new Mo bronzes. The crystal structure of the present crystal belongs to the type similar to that of the purple bronze NaoyMo60n [1,2], but it distinctly differs from the latter in such points as the doubly-sized b axis, the composition and the behaviour of the electrical conductivity. We report here the preparation, the crystal structure and the temperature dependence of the electrical conductivity.
