Abstract

Single crystals of Ca(HO3PC6H5)2 (1) and Sr(HO3PC6H5)2 (2) have been obtained via the crystallization of their respective amorphous powders. The amorphous compounds were synthesized by traditional solution routes and were subsequently crystallized at 160°C in a Teflon-lined autoclave containing 1–3 mL distilled water. The resultant single crystals were physically isolated and their structures determined by single crystal X-ray diffraction. The two compounds are isostructural and crystallize in space group C2/c with lattice parameters of a = 31.267(3) Å, b = 5.6185(6) Å, c = 7.7202(8) Å, β = 101.924(2)°; and a = 31.514(4) Å, b = 5.8098(8) Å, c = 7.8218(10) Å, β = 102.063(3)° for the calcium and strontium phenylphosphonate, respectively.
