Piperazinium hydrogenarsenate monohydrate

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

Abstract: In the title compound, C₄H₁₂N₂²⁺·HAsO₄^2-·H₂O, the component species interact by way of N-HO and O-HO hydrogen bonds, the latter leading to infinite sheets of HAsO₄^2- anions and water molecules containing R₆⁶(18) loops. The asymmetric unit contains one anion, one water molecule and half each of two centrosymmetric cations.
