A new copper iodide/organic hybrid incorporated with methyl viologen, [(MV)(Cu_2I_4)·H_2O]_n(1, MV = methyl viologen), has been solvothermally synthesized and structurally determined by X-ray diffraction method. 1 crystallizes in tetragonal system, space group P42212 with M_r = 838.95, a = 12.4721(18), c = 6.5892(13 ?, V = 1025.0(3) ?~3, Z = 2, Dc = 2.7125 g/cm~3, F(000) = 756, μ(Mo Kα) = 8.097 mm–1, the final R = 0.0273 and wR = 0.0665 for 1062 observed reflections with I > 2σ(I). In 1, the(Cu_2I_4)_n~(2n-) chain was constructed from edge-sharing of distorted Cu I4 tetrahedra. Its absorption spectrum and photoluminescence were investigated, and energy band gap of 1.76 e V indicates its semiconductor nature. Interestingly, 1 exhibits photocatalytic activity for the degradation of rhodamine B.

Its absorption spectrum and photoluminescence were investigated, and energy band gap of 1.76 e V indicates its semiconductor nature. Interestingly, 1 exhibits photocatalytic activity for the degradation of rhodamine B.
