Figure 4
A view of part of the crystal structure of (II), showing the formation of two chain motifs spreading parallel to [100] and [001]. Hydrogen bonds are drawn as dotted lines and C-bound H atoms have been omitted. Atoms marked with the suffixes a, b and c are at the symmetry positions (x + , −y + 1, −z + ), (x − , −y + 1, −z + ) and (−x + , y, z + ), respectively. |
