Bis(benzylammonium) hydrogenarsenate monohydrate

C. Lee and W. T. A. Harrison

Abstract: The title compound, (C₆H₅CH₂NH₃)₂[HAsO₄]·H₂O, contains a network of benzylammonium cations, hydrogenarsenate anions [d_av(As-O) = 1.689 (2) Å] and water molecules. The crystal packing involves N-HO [d_av(HO) = 1.91 Å, _av(N-HO) = 167° and d_av(NO) = 2.794 (3) Å] and O-HO [d_av(HO) = 1.83 Å, _av(O-HO) = 173° and d_av(OO) = 2.729 (3) Å] hydrogen bonds, resulting in a layered structure.
