Abstract
Single crystal samples of a stage 1 compound of AuCl3-graphite have been investigated by X-ray diffraction. The 001 patterns show a lattice parameter c(1) of 683 pm. The received hk-pattern can be interpreted by an oblique angled in-plane lattice with lattice parameters: a = 1288 pm, b = 655 pm and γ=112.5°, commensurate with the graphite lattice. This in-plane cell is nearly identical with the a-c lattice plane of pristine Au(III)-chloride. Therefore, we consider that AuCl3-graphite is built up of the same planar units Au2Cl6 as they are found in pristine Au(III)-chloride. Angle dependent EXAFS and XANES measurements of HOPG samples indicate the tilting of the planar molecules by an angle of ca. 15° with respect to the graphite layers.
