A multifunctional organic–inorganic hybrid based on a Cu coordination polymer capped polyoxometalate (H3PMo12O40) designated as compound 1 with [CuI(4,4-bipy)]3[PMo 10 VI Mo 2 V O40{CuII(2,2-bipy)}] formula was prepared using CuCl2·2H2O, 4,4-bipy, 2,2-bipy and H3PMo12O4 in water under hydrothemal conditions. The prepared compound 1 was characterized by FTIR, XRD and chemical analysis techniques. It was found that the compound successfully catalyzes the epoxidation of various alkenes such as diphenyl ethylene, trans-stilbene, cyclohexene, norbornene, styrene and cyclooctene and oxidation of alkanes such as fluorene, adamantane, diphenylmethane, cyclohexane and cyclooctane, in acetonitrile with 20-9?% conversion and 53-00?% selectivity with tert-butyl hydroperoxide as oxidant under optimized condition. This heterogeneous catalyst could be easily recovered and reused after reaction without loss of activity.
