    • The front direction probably corresponds to the c direction (i.e., the direction of the 1-D supramolecular chains). The faces found at the edges of the longest dimension of the crystal were difficult to index since their indices seemed to vary. Near room temperature, these faces were approximately (104) and (104) but should have been (102) and (102) since the normal to these planes is found nearly along the c direction.

    • The infrared spectrum of various samples of type (a) are always identical to that of crushed single crystals of 1 [i.e., sample (b) after grinding], and their powder X-ray diffraction spectrum at room temperature (Figure 6) fits well with the spectrum calculated for phase I.

    • The small variations of T the HS phase after each cycle (as shown in Figure 5) can be interpreted as a small displacement of the loosely packed crystals in the sampler holder until the most stable arrangement is attained.
