Crystal Structure and Reflectance Spectrum of β″-(BEDT-TTF)2IAuBr

Abstract
(BEDT-TTF)2IAuBr was synthesized and the crystal structure of this material was determined to be of the β″- type, being isomorphous to β″-(BEDT-TTF)2AuBr2. The polarized reflectance spectrum indicates that the electronic structure of this salt is of considerable two-dimensional character.
