Arsole is the arsenic analogue of the unsaturated five-membered heterocycles pyrrole and phosphole. Pure arsole has not been isolated, but theoretical studies show that it has much less aromatic character than pyrrole, and that, unlike pyrrole, its (and phosphole's) heteroatom-bonded hydrogen atom extends out of the plane formed by the carbon atoms.
