Synthesis and Crystal Structure of a New Organic 4-Chloroanilinium Dihydrogenomonoarsenate: (4-ClC₆H₄NH₃)H₂AsO₄

Abstract

The chemical preparation and crystal structure are given for a new organic-cation dihydrogenomonoarsenate, (4-ClC₆H₄NH₃)H₂AsO₄, in the solid state. This compound crystallizes in the monoclinic space group P2₁/a with the following unit-cell parameters: a = 8.339(5)Å, b = 9.434(3)Å, c = 12.630(4)Å, β = 102.28(4)°, Z = 4 and V = 970.8(7)ų. The crystal structure was solved with a final R = 0.05 using 2922 independent reflections. The atomic arrangement can be described as two-dimensional inorganic thick layers spreading around the z = 0 plane. The organic entities are anchored to the inorganic layers through N-H…O hydrogen bonds.
