Figure 2
(a) The packing in (I), showing the two-dimensional structure parallel to (100). For clarity, no solvent molecules or H atoms are shown. (b) A projection of the layers shown in (a), at right angles to the former view, as well as their interaction via hydrogen bonding (dashed lines). Note the hydrogen-bonding loops formed, viz. an R64(12) ring (denoted A) and an R22(8) ring (denoted B). (c) A detailed view of the chain of hydrogen-bonded rings described in (b) shown in the same orientation. |
