Figure 3
A packing diagram for (I), showing part of the two-dimensional hydrogen-bonded network derived from crosslinkage of the one-dimensional chains via N5—H5A⋯O4# hydrogen bonds. Atoms labelled with a dollar sign ($), an ampersand (&) or a hash (#) are at the symmetry positions (−x + 2, −y, −z + 1), (−x + 2, −y + 1, −z + 1) and (−x + , y + , −z + ), respectively. |
