Abstract In the present work, we have isolated di-copper substituted phosphotungstate, Cs7[PW10Cu2(H2O)2O38]·9H2O, as a single isomer using novel microwave technique from the commercially available H3PW12O40 and CuCl2. The same compound has been synthesized using one pot synthesis method as well. Further, we have shown that our product does not contain any isomer by the virtue of 31P NMR spectrum which shows only one signal. Using various physicochemical techniques, we have also shown that the complexes synthesized by both the techniques are the same. The complex was used as a heterogeneous catalyst for the selective epoxidation of cis-cyclooctene with TBHP as the oxidant.
