Abstract
A structural study of CsCuCl3, grown from aqueous solution, was perfor med using anomalous x-ray scattering near the Cs K absorption edge to determine an absolute configuration of constituent atoms. The sense of the helical structure of the CuCl3 chain was found to be predominantl y right-handed through a comparison of observed Bragg Bijvoet ratios w ith calculated ones. Assuming that CsCuCl3 consists of the two domains (i.e. right- and left-handed helices), we estimate that the volume fr action for the right-handed helix is 0.87 +/- 0.02.
