Molybdenum diarsenideis anarsenideofmolybdenum,with the chemical formula MoAs2.Other arsenides of molybdenum are Mo2As3and Mo5As4.[2][3]
Preparation[edit]
Molybdenum diarsenide can be prepared by the reaction ofmolybdenumandarsenicat 570 °C.[1]
Properties[edit]
Molybdenum diarsenide is a black solid,[1]and is asuperconductorat 0.41 K.[4]It crystallises in themonoclinic crystal system,with space group (No. 12).[5]It has the same structure asmolybdenum diphosphide.It is insoluble in concentratedhydrochloric acidorhydrogen peroxide,but easily soluble innitric acid,hot concentratedsulfuric acidandaqua regia.[6]
