    • The structure of Sr14 (unit cell a = 14.82, b = 15.12, c = 17.09 Â, a = 109.86, /3 = 111.66, γ = 100.82°) is believed to be very similar to that of Cal4 but extensive crystal twinning precludes full analysis.

    • Interestingly, introducing a Li cation to the calculations does give the expected para > meta > ortho order for the total sulfonate Oatom charges (-1.536, -1.534 and -1.502, respectively). However, the optimized Li ortto-sulfonate geometry has Li bonded to both the sulfonate and the azo groups. Thus the model does not accurately reflect the experimentally observed geometry.
