Title: Synthesis and crystal structure of a mixed alkaline-earth powellite, Ca 0.84Sr 0.16MoO 4

Abstract

A mixed alkaline-earth powellite, Ca 0.84Sr 0.16MoO 4 (calcium strontium molybdate), was synthesized by a flux method and its crystal structure was solved using single-crystal X-ray diffraction (SC-XRD) data. The compound crystallized in the I4 1/a space group as with a typical CaMoO 4 powellite, but with larger unit-cell parameters and unit-cell volume as a result of the partial incorporation of larger Sr cations into the Ca sites within the crystal. The unit cell and volume were well fitted with the trendline calculated from literature values, and the powder X-ray diffraction (P-XRD) pattern of the ground crystal is in good agreement with the calculated pattern from the solved structure.
