Figure 3
A view of the two-dimensional hydrogen-bonded network of (I) parallel to the (010) plane, showing the aggregation of three hydrogen-bonding motifs, viz. C(8), C21(4) and R32(8). Hydrogen bonds are drawn as dotted lines and C-bound H atoms have been omitted. Atoms marked with an ampersand (&), an `at' sign (@), a hash symbol (#) or a dollar sign ($) are at the symmetry positions (2 + x, y, z), (1 + x, y, z), (x, − y, + z), (2 + x, − y, + z), respectively. |
