The X‐ray crystal structure of 5‐methyl‐5,10‐dihydrophenarsazine, C 13 H 12 NAs, has been determined. The crystals are orthorhombic, space group P2 1 2 1 2 1 , a = 8.511(4), b = 5.690(1), c = 23.535(9) Å, V = 1139.7(1.0)A 3 , and Z = 4. Least‐squares refinement converged to R = 0.049 and Rw = 0.045. The central ring is in a boat conformation and the 5‐methyl group is in the axial position with respect to the central ring. The folding angle between the planes of the two benzo rings is 154.1(4)°.
