Description:
TheN,N-dimethylethylamminium unit inN,N-dimethyl-[2-(2,2-diphenyl)-2-prop-2-ynyloxyacetoxy]ethylamine, C21H23NO3(I), is disordered over two sets of atomic sites having occupancies of 0.880 (3) and 0. 120 (3), but there are no direction-specific interactions between the molecules of (I). The cation inN,N-dimethyl-[2-(2,2-diphenyl)-2-prop-2-ynyloxyacetoxy]ethylammonium 2,4,6-trinitrophenolate (picrate), C21H24NO3+·C6H2N3O7−(II), shows a similar type of disorder, with occupancies of 0.654 (11) and 0.346 (11), although the overall conformation of the cation in (II) is different from that in the neutral (I). The component ions are are linked by an almost planar three-centre N—H...(O)2hydrogen bond, and the ion pairs are further linked by a combination of three C—H...O hydrogen bonds to form sheets. Comparisons are made with some related structures.
