Chemical compound
Molybdenum diarsenide is an
arsenide of
molybdenum, with the chemical formula MoAs2. Other arsenides of molybdenum are Mo2As3 and Mo5As4.
[2]
[3]
Preparation
Molybdenum diarsenide can be prepared by the reaction of
molybdenum and
arsenic at 570 °C.
[1]
Properties
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.
