An X-ray diffraction stvrdy of KBI0.64(N02)0.36 was performed to elucidate its strtrcttnral glass-like properties and compare them to those of' otlaer tnixed crystals. As the ternperature decreases,the fundautaental Bragg reflectiorxs begin to decreatse and strong diffused scattering apjcearsaround the Brillouin-zone center of an f'ace centered ctrlcic (fcc) lattice, f-point. The resultsindicate that the local distortion of' a lattice with only short-range ferroelectric correlation isindtmced by reorient;rtional f'reezing of nitrile ions. Tlae correlation length estitnated from thediffused scattering is about 23 A at TOO K, which is navxch smaller than the coheretace length ofan X-ray.
