摘要

The N,N-di#173;methyl#173;ethylamminium unit in N,N-dimethyl-2-(2,2-diphen#173;yl)-2-prop-2-ynyloxyacet#173;oxyethyl#173;amine, C21H23NO3 (I), is disordered over two sets of atomic sites having occupancies of 0.880#8197;(3) and 0. 120#8197;(3), but there are no direction-specific inter#173;actions between the mol#173;ecules of (I). The cation in N,N-dimethyl-2-(2,2-diphen#173;yl)-2-prop-2-ynyloxyacet#173;oxyethyl#173;ammonium 2,4,6-tri#173;nitro#173;phenolate (picrate), C21H24NO3+#183;C6H2N3O7#8722; (II), shows a similar type of disorder, with occupancies of 0.654#8197;(11) and 0.346#8197;(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#8212;H#8943;(O)2 hydrogen bond, and the ion pairs are further linked by a combination of three C#8212;H#8943;O hydrogen bonds to form sheets. Comparisons are made with some related structures.
