Synthesis of vanadyl(IV) organophosphonates VORPO{sub 3}{center_dot}nH{sub 2}O (with R = CH{sub 3}, C{sub 2}H{sub 5}, C{sub 6}H{sub 5}) has been investigated by reaction of VOSO{sub 4}{center_dot}5H{sub 2}O + RPO{sub 3}H{sub 2} under refluxing conditions in aqueous media. The influence of different parameters is discussed, and compounds are characterized by X-ray powder diffraction, TGA, IR, XANES, and EXAFS. For example, three crystallographic forms of VOC{sub 6}H{sub 5}PO{sub 3}{center_dot}2H{sub 2}O obtained differ from each other in the location of the trans water molecule in the layered structure.
