A 3D Porous Framework Constructed from [(piiio3)2mo5o15]6− Clusters and {cu(en)2} Units: Synthesis, Crystal Structure and Electrochemical Properties

1A new hybrid was prepared via in situ self-assembly synthesis method.2CuenP2Mo5 presents 3D porous framework formed by linking [(PIIIO3)2Mo5O15]6− clusters with {Cu(en)2} units.3CuenP2Mo5 shows good electrocatalytic activity for the reduction of H2O2.4CuenP2Mo5-CPE exhibits fast response, wide detection range, and high sensitivity for H2O2 detection.A novel inorganic-organic hybrid presents a 3D porous framework constructed from the [(PIIIO3)2Mo5O15]6− clusters and {Cu(en)2} units, which shows electrochemical sensing performance for the detection of H2O2.
