Structure of MAP:MNA, the 1:1 adduct between (R)-methyl 2-(2,4-dinitroanilino)propanoate (MAP) and 2-methyl-4-nitroaniline (MNA), a new nonlinear optical crystal

Among innumerable organic materials investigated for their exceptional nonlinear optical (NLO) properties 2-methyl-4-nitroaniline (MNA) has one of the largest second-order nonlinear coefficients, χ(2)(d12 = 38 and d11 = 250 pm/V),1 crystallizing in the monoclinic space group Cc.1 Large crystals of MNA could not be grown from either solution or melt. Therefore, we tried crystallizing mixtures of methyl-(2,4-dinitriphenyl)-aminopro-panoate (MAP) and MNA2 from organic solutions. Large prismatic orange-red colored crystals of an equimolar complex crystallized in the monoclinic space group P21 with lattice parameters different from those of either MAP or MNA.3 The color, ascribed to a band starting at 530-nm, reduced second-harmonic generation (SHG) efficiency.3 Therefore, MAP was substituted by the precursor in its synthesis, (2,4-dinitrophenyl)-L-alanine (DPA).4
