Crystal structure of the complex of 1,8-bis (dimethylamino)naphthalene with p-nitrosophenol by powder diffraction methods

Crystal structure solution of organic compounds without heavy atoms by powder diffraction method is still a challenging task, particularly when there is not a rigid group in the compound, or when there are more than one molecule in the asymmetric unit. In this paper the crystal structure solution of the complex of 'proton sponge' 1,8-bis (dimethylamino)naphthalene (DMAN) and p-nitrosophenol: C₁₄H₁₉N₂⁺. C₆H₄(NO)O^–. C₆H₅(NO)OH is presented. This structure, with 25 atoms and three independent molecules in the asymmetric unit, was solved from powder data by ´pseudo-atom´ method. The space group Pnma, Z=4, a=12.2125(5) Å, b=10.7524(7) Å, c=18.6199(14) Å, R_wp and R_F are 12.8 and 16.0, respectively.
