Iodoplumbate(Ⅱ)-based Hybrid Templated by 1,4-Diazabicyclo[2.2.2]octane Derivative:Structure,Photocurrent Response Behavior and Photocatalytic Activity for the Degradation of Organic Dye

A new iodoplumbate/organic hybrid,(Et_2DABCO)_2(Pb_3I_(11))(H3 O)]n(1,Et_2DABCO = N,N?-diethyl-1,4-diazabicyclo2.2.2] octane) has been synthesized using solution method.According to X-ray diffraction structural analysis,the unique(Pb_3I_(11))_n~(5n-) chain in 1 is constructed from face-and edge-sharing PbI_6 octahedra,which is templated by(Et_2DABCO)~(2+) dication possessing both rigidity and flexibility.C–H···I hydrogen bonds contribute to the structure extending from 1D chains to a 3D network.Its energy band gap of 2.64 eV indicates its broad-gap semiconductor nature.It exhibits both photocurrent response property and photocatalytic activity for the degradation of rhodamine B.
