Two [Co(bipy)]-Templated Silver Halobismuthate Hybrids: Syntheses, Structures, Photocurrent Responses, and Theoretical Studies.

Employing in situ-generated metal complexes as structural decorating agents, we, for the first time, isolated two [Co(bipy)]-templated silver halobismuthate hybrids, namely [Co(bipy)]AgBiX (X = Br (), I (); bipy = 2,2'-bipyridine). Compounds and belong to the isomorphic phrases and exhibit the nonperovskite structures characteristic of the discrete [AgBiX] anions. UV-vis absorption spectra analyses showed that the optical band gaps of compounds and are 2.40 and 1.95 eV, respectively, implying the visible light responding semiconductor properties. Moreover, under the alternate light illumination, the title compounds exhibited "on/off" photocurrent behaviors, with high photocurrent densities comparable to many metal halide hybrids. Presented in this work also involved the Hirshfeld surface analyses and X-ray photoelectron spectroscopy studies together with the theoretical band structures, density of states, and electron wave functions.
