Single crystals of (p-ClC{sub 6}H{sub 4}NH{sub 3})H{sub 2}PO{sub 4} are synthesized in water by interaction of H{sub 3}PO{sub 4} and (p-ClC{sub 6}H{sub 4}NH{sub 2}). This compound crystallizes in the orthorhombic system with the Pbca space group. Its unit-cell parameters are a = 9.724(3), b = 7.861(1), c = 25.078(6) A, V = 1917.1(6) A{sup 3} and Z = 8. The crystal structure has been solved and refined to R = 0.039, using 4298 independent reflections. The atomic arrangement can be described by inorganic layers parallel to ab plane, between which the organic cations are located. This compound exhibits a reversible phase transition at 403 K. The electrical conductivity measurements show that the (p-ClC{sub 6}H{sub 4}NH{sub 3})H{sub 2}PO{sub 4} has a conductivity value which goes from {sigma} = 0.88 x 10{sup -6} {omega}{sup -1} cm{sup -1} at room temperature (293 K) to 3.31 x 10{sup -4} {omega}{sup -1} cm{sup -1} at 433 K. Its characterisation by TA, NMR and IR is reported too.
