Structure analysis shows that the compound consists of organic cations(Methyltriethylammonium) and inorganic anion chains (Ag2I3)n-. The inorganic moiety consists of AgI4 tetrahedron, which shares the same edges with adjacent AgI4 tetrahedrons to form one-dimensional infinite double chains along a-axis. There exists weak interaction among Ag…Ag atoms in the crystal. Anion chains are surrounded by Methyltriethylammonium cations. Anion chains and cations are in combination with each other by static attracting forces in the crystal to form so-called organic-inorganic hybrid structure. According to the crystal structure data, quantum chemistry calculation with DFT on B3LYP level was used to reveal the electronic structure of title compound. CCDC: 254288.展开更多
