==制备与性质==
一砷化镎可由[[砷]]和[[镎]]的化合反应制得：
::<math>\mathsf{ Np + As \ \xrightarrow{T, I_2}\ NpAs }</math>

它在不同条件下可以形成多种晶体结构：<ref>{{cite web |title=mp-2186: NpAs (cubic, Fm-3m, 225) |url=https://materialsproject.org/materials/mp-2186/ |publisher=[[Materials Project]] |access-date=8 August 2021 |archive-date=2021-08-08 |archive-url=https://web.archive.org/web/20210808195952/https://materialsproject.org/materials/mp-2186/ }}</ref><ref>{{cite journal |last1=Arya |first1=Balwant Singh |last2=Patle |first2=U.
