Figure 2
Schematic view of the packing showing the elemental `dimeric unit' formed around the center of symmetry at (½,½,½), and the way in which it interacts with symmetry-related neighboring `dimers' (A, B, A′ and B′). For clarity, the bulky biquinoline group has been idealized by the N—C—C—N loop. Heavy broken lines represent hydrogen bonds of the first group in Table 2 ![[link]](../../../../../../logos/arrows/c_arr.gif) which define the `dimers', while dotted lines represent hydrogen bonds of the second group which link symmetry-related neighboring `dimers'. [Symmetry codes: (A) x − 1, y, z; (B) x − ½, −y − ![[3 \over 2]](teximages/bk1615fi4.gif) , z − ½; (A′) −x + 2, −y + 1, −z + 1; (B′) −x + , y − ½, −z + .] |
