Abstract

A solid solution was found to exist in the quaternary Li ₂O-MgO-V₂O₅-MoO₃ system between the two phases Mg_2.5VMoO₈ and Li₂Mg ₂(MoO₄)₃. Both Mg_2.5VMoO₈ and Li₂Mg₂(MoO₄)₃ are isostructural with the mineral lyonsite, and substitution according to the formula □_1/4-x/6Li_4x/3Mg_15/4-7x/6V _3/2-xMo_3/2+xO₁₂ (0 ≤ x ≤ 1.5, where □ denotes a cation vacancy) demonstrates that a complete solid solution exits coupling the addition of molybdenum and lithium with the subtraction of cation vacancies, magnesium, and vanadium and vice versa. Vibrational Raman spectroscopy indicates that molybdenum-oxo double bonds preferentially associate with the cation vacancies.
