Molybdenum diarsenide is an arsenide of molybdenum, with the chemical formula MoAs2. Other arsenides of molybdenum are Mo2As3 and Mo5As4. [2] [3]
Molybdenum diarsenide can be prepared by the reaction of molybdenum and arsenic at 570 °C. [1]
Molybdenum diarsenide is a black solid, [1] and is a superconductor at 0.41 K. [4] It crystallises in the monoclinic crystal system, with space group (No. 12). [5] It has the same structure as molybdenum diphosphide. It is insoluble in concentrated hydrochloric acid or hydrogen peroxide, but easily soluble in nitric acid, hot concentrated sulfuric acid and aqua regia. [6]
