New strontium phenylphosphonate dihydrate with formula SrC6H5PO3⋅2H2O was prepared and characterized by elemental analysis, TGA, and powder XRD. The compound crystallizes in an orthorhombic system with cell parameters a=14.280(2)a=14.280(2), b=8.608(1)b=8.608(1), c=7.918(1) Åc=7.918(1) Å and a space group P2221 (No. 17). A thermal behavior of SrC6H5PO3⋅2H2O was studied and powder XRD patterns and cell parameters of compounds obtained by its dehydration, that is SrC6H5PO3⋅H2O and SrC6H5PO3, are described. The infrared spectra of SrC6H5PO3⋅2H2O are discussed and compared with the spectra of phenylphosphonic acid, SrC6H5PO3, and Sr(C6H5PO3H)2. A transformation of SrC6H5PO3⋅2H2O into Sr(C6H5PO3H)2 in an acid medium and an opposite transformation of Sr(C6H5PO3H)2 into SrC6H5PO3⋅2H2O in a basic medium were also investigated.
