tert-Butylammonium dihydrogenarsenate

H. S. Wilkinson and W. T. A. Harrison

Abstract: The title compound, (C₄H₁₂N)[H₂AsO₄], contains a network of tert-butylammonium cations and dihydrogenarsenate anions [d_av(As-O) = 1.682  (2)  Å]. The crystal packing involves N-HO [d_av(HO) = 1.96  Å, _av(N-HO) = 169° and d_av(NO) = 2.837  (3)  Å] and O-HO [d_av(HO) = 1.68  Å, _av(O-HO) = 169° and d_av(OO) = 2.626  (2)  Å] hydrogen bonds, resulting in a layered structure.
