The crystal structure of the polymer–salt complex [(CH2CH2O)n]∶KCF3SO3 has been obtained from powder diffraction data collected on a laboratory X-ray diffractometer. Profile refinement was employed in the structure elucidation, based on a model of the previously known structure of [(CH2CH2O)n]∶NaCF3SO3.
