Abstract

The Lewis acidic ionic liquid EMIMBr-AlCl₃ (EMIM = 1-ethyl-3-methylimidazolium) allows a novel synthetic route to the semiconducting layered metal chalcogenides halide [Bi₂Te₂Br]-(AlCl₄) and its Sb analogue. [Bi₂Te₂Br](AlCl₄) is a direct band gap, strongly anisotropic semiconductor and consists of cationic infinite layers of [Bi₂Te₂Br]⁺ and [AlCl₄]^- anions inserted between the layers. © 2010 American Chemical Society.
