Abstract:
Two iodoargentate hybrids templated by viologen or viologen-like cations, i.e. [MV(Ag2I4)](n) (1) and [MBYP(AgI2)](n) (2), (MV2+ = methyl viologen, MBYP+ = 1-methyl-2,2'-bipyridine) have been synthesized in polar organic solvents. (Ag2I4)(n)(2-) and (AgI2)(n)(2-) chains in both compounds were constructed from edge-sharing of normal and distorted AgI4 tetrahedra, and a 2-D supramolecular layer based on C-H center dot center dot center dot I hydrogen bond was observed in 1. The band gaps of 1.54 and 2.67 eV indicated their semiconductor nature. Their band gap difference was led by different hydrogen bond donors in MV2+ and MBYP+, which result in more diffused p-pi* antibonding orbitals in MV2+.
