A new iodobismuthate-based hybrid (Me(2)DABCO)(7)(BiI6)(2)(Bi2I9)(2).2I(3) (1) (Me(2)DABCO(2+) = N,N'-dimethyl-1,4- diazabicyclo[2.2.2] octane) has been structurally determined. The highly interesting feature of 1 lies in its presence of mixed types of iodobismuthate clusters, i.e. mononuclear (BiI6)(3-) and (Bi2I9)(3-) dimer in one crystal lattice templated by Me(2)DABCO(2+) cation, which is the first example of mixed iodobismuthate clusters in one lattice. Its absorption zone can be broadened compared with other single iodobismuthate cluster-containing analogy compounds. And due to the strong I center dot center dot center dot I interactions, an optical gap of 1.61 eV can be observed. The photocurrent response properties before and after heating were discussed, which suggests that the device can be potentially used as temperature-response switch.
