Abstract:	Reactions of BiI₃, copper or silver iodide and 4-(dimethyl-amino)-1-methylpyridinium iodide [(Me-DMAP)I] result in formation of heterometallic complexes (MeDMAP)₂{[Bi₂Cu₂I₁₀]} and (MeDMAP)₂{[Bi₂Ag₂I₁₀]}. Their crystal structures, thermal stability and optical properties have been studied. Optical band gaps calculated from diffuse reflectance spectroscopy data are 1.81 and 2.06 eV for copper- and silver-containing complexes, respectively.

Keywords:	bismuth copper silver halide complexes semiconductors
