An　iodoargentate　hybrid　coordination　polymer　induced　by　MV2+,　[MV(Ag2I4)]　n　(1)　(MV　=　methyl　viologen,　i.e.,　1,1-dimethyl-4,4-bipyridinium),　has　been　obtained　and　structurally　determined.　In　1,　(Ag2I4)　n　2-　chain　exhibits　a　new　type　of　zigzag-like　configuration　constructed　from　edge-sharing　of　normal　and　distorted　AgI4　tetrahedra,　hydrogen　bonds　between　MV2+　cations　and　(Ag2I4)　n　2-　chains　contributed　to　the　formation　of　quasi-two-dimensional　structure.　The　band　gap　of　2.12　eV　based　on　optical　absorption　spectrum　indicated　its　semiconductor　nature.　Quantum　chemistry　calculation　with　DFT　method　was　carried　out　to　reveal　its　electronic　structure.　©　2011　Springer　Science+Business　Media,　LLC.
