Description	4-Sulfophenylphosphonic acid was successfully used for the preparation of zirconium sulfophenylphosphonate and zirconium phosphate sulfophenylphosphonate with formulae Zr(HO3SC6H4PO3)2.2H2O and Zr(HPO4)0.7(HO3SC6H4PO3)1.3.2H2O. Both compounds were further characterized by FTIR and solid-state NMR, which confirmed the presence of strongly acidic hydrogen on the sulfonic group. The proton conductivity of both compounds was determined as a function of relative humidity and as a function of temperature. Due to their insolubility in water, good thermal stability and the considerably high protonic conductivity the discribed layered compounds are promising candidates for application as components of composite proton exchange membranes in fuel cells. 4-Sulfophenylphosphonic acid was successfully used for the preparation of zirconium sulfophenylphosphonate and zirconium phosphate sulfophenylphosphonate with formulae Zr(HO3SC6H4PO3)2.2H2O and Zr(HPO4)0.7(HO3SC6H4PO3)1.3.2H2O.
