The sample was measured in the Bragg–Brentano
geometry with variable slits and the PIXcel detector, in the 2θ
range from5° to 80°. Powder diffraction patternsweremeasured
with the step size of 0.0263° 2θ; total integrating time for one
step was 180 s. Incident beam was conditioned by Soller slit
(divergence 0.04 rad) and a beam mask of width 5 mm was
used.
