The title compound was synthesized and its crystal structure was determined. The crystals are triclinic in the space group P1 with α = 0.80284 (8) nm, b = 0.95993 (6) nm, c = 0.71660 ), Β = 111.933 (9) °, γ = 101.650 (8) °, V = 0.4767 (1) nm to 3, Z = 1 and Dc = 3.21 g · cm -3. 404, μ (MoKa) = 98.77cm ~ (-1). There are trans-planar 2,2’-bipyH 2 2+ and I 3 anions in the crystal, ’-bipyH_2) (I_3) _2] _∞ chains, N-H ··· hydrogen bonds exist between the chains of the same layer with a hydrogen bond length of 0.349 nm.Using UV-Vis spectroscopy The title compound was characterized by ~ 1H NMR spectroscopy.
