A packing diagram for (II) (MERCURY; Bruno et al., 2002), viewed along (100). Molecules A and B are labeled at the cytosine base; dotted lines represent hydrogen bonds. The asterisks (*) and hashes (#) represent the symmetry operations (x + 1, y − 1, z) and (x − 1, y − 1, z), respectively. Crosses (+) represent overlapped atoms along the projection axis. |
