Dibenzylammonium hydrogen maleate and a redetermination at 120 K of bis(dibenzylamino)methane

J. C. Castillo, R. Abonía, J. Cobo and C. Glidewell

Abstract: In dibenzylammonium hydrogen maleate [or dibenzylammonium (2Z)-3-carboxyprop-2-enoate], C14H16N+·C4H3O4-, (I), the anion contains a fairly short and nearly linear O-H...O hydrogen bond, with an O...·O distance of 2.4603 (16) Å, but with the H atom clearly offset from the mid-point of the O...O vector. The counter-ions in (I) are linked by two N-H...O hydrogen bonds to form C22(6) chains and these chains are weakly linked into sheets by a C-H...O hydrogen bond. Bis(dibenzylamino)methane, C29H30N2, (II), crystallizes with two independent molecules lying across twofold rotation axes in the space group C2/c, and the molecules are conformationally chiral; there are no direction-specific intermolecular interactions in the crystal structure of (II).

Formula: C14H16N+·C4H3O4- and C29H30N2
