Figure 3 Representation of part of the lattice contents of (I), along the a axis, showing the hydrogen-bonded chains. Only selected interactions are shown for clarity. Atoms involved in hydrogen bonds are shown as balls of arbitrary radii. All other atoms and covalent bonds are represented as wires or sticks. [symmetry code: (i) 1–x, 1–y, 1–z; (ii) 1/2–x, 1/2+y, 3/2–z; (iii) 1/2+x, 1/2–y, −1/2+z]. |
