Abstract

Variable-temperature high-resolution capillary-mode powder X-ray diffraction is used to assess changes in unit-cell dimensions as a function of temperature over the range 188-328 K. No evidence was found for any polymorphic transformations over this temperature range and thermal expansion coefficients for urea were found to be aa = (5.27 ± 0.26) × 10-5 K-1 and ac = (1.14 ±0 .057) × 10-5 K-1. © 2005 International Union of Crystallography - all rights reserved.
