Crystal structure of dibenzylammonium hydrogen (4-aminophenyl)arsonate monohydrate

The title salt, C14H16N+ · C6H7AsNO3 − · H2O or [(C6H5CH2)2NH2][H2NC6H4As(OH)O2] · H2O, (I), was synthesized by mixing an aqueous solution of (4-aminophenyl)arsonic acid with an ethanolic solution of dibenzylamine at room temperature. Compound I crystallizes in the monoclinic P21/c space group. The three components forming I are linked via N — H...O and O — H...O intermolecular hydrogen bonds, resulting in the propagation of an infinite zigzag chain. Additional weak interactions between neighbouring chains, such as π – π and N — H...O contacts, involving phenyl rings, – NH2 and – As(OH)O3 functions, and H2O, respectively, lead to a three-dimensional network.
