Synthesis of a two-dimensional organic–inorganic bismuth iodide metalate through in situ formation of iminium cations†
Abstract
(Me2CNMe2)Bi2I7 represents a new layered organic–inorganic iodido bismuthate. It displays an unprecedented anion topology, a low band gap and good stability. Advanced electronic structure analysis finds the I⋯I interactions to be decisive for the compound's structural and electronic properties.
