Abstract

A novel method involving a molten Ga flux for the synthesis of diffraction quality crystals of the compound Cu_3.82(1)Mo₃O ₁₂, a copper molybdate in the Lyonsite (α-Cu₃Fe ₄(VO₄)₆) family, has been developed. Single-crystal X-ray diffraction data have been collected. Cu _3.82(1)Mo₃O₁₂ crystallizes in the space group P2₁2₁2₁ with cell dimensions of a=4.9972(1) Å, b=11.0259(3) Å, and c=17.4912(5) Å. Refinement of the resulting structure has enabled modeling of disorder in the channels of the structure and has indicated the localization of copper vacancies to these channel positions. Thermopower measurements indicate that Cu _3.82(1)Mo₃O₁₂ is a rare and interesting example of a cation-deficient n-type material.
