SQUEEZE suggests 357e/cell, which is 89.3e/asu.
Solvent was said to be dcm (CH2Cl2), which has 42e.
asu contains 2 macrocycles, so 89e/asu = 44.5e/macrocycle.
This is close to 1 dcm/macrocycle so this was considered to be
the solvent present.

asu thus 2dcm low = C2 H4 Cl4, so UNIT C8 H16 Cl16 low,
i.e. C288 H192 O32 S32
