Abstract

A novel method involving a molten Ga flux for the synthesis of diffraction quality crystals of the compound Cu _3.82(1) Mo ₃ O ₁₂ , a copper molybdate in the Lyonsite (α-Cu ₃ Fe ₄ (VO ₄ ) ₆ ) family, has been developed. Single-crystal X-ray diffraction data have been collected. Cu _3.82(1) Mo ₃ O ₁₂ crystallizes in the space group P2 ₁ 2 ₁ 2 ₁ 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) Mo ₃ O ₁₂ is a rare and interesting example of a cation-deficient n-type material.
