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 2.4603â
(16)â
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 C2(2)(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).
