Figure 7
The inclination angle between the least-squares plane fitted to atoms O(1), O(2), C(1)–(6) and crystal plane (001), $[\varphi]$ ; and the temperature dependence of the closest interchain contacts of atom C(5): to O atoms O(1ⁱⁱ) and O(1ⁱⁱⁱ). The symmetry codes are: (ii) 1 − x, 1 − y, −z and (iii) ½ + x, 1 − y, ½ − z for the low-temperature phase below 244 K; (ii) ½ − x, ½ − y, ½ − z and (iii) ½ + x, ½ − y, −z for the high-temperature phase above [T_c]

. The thin and dotted lines are drawn as a guide to the eye.
