Figure 5
Part of the crystal packing of (II), showing the hydrogen-bonded R43(29) rings fused together to form chains. Hydrogen bonds are shown as dashed lines and H atoms not involved in hydrogen bonding have been omitted for clarity. Selected atoms of the molecules present in the asymmetric unit are labelled, primarily to provide a key for the coding of the atoms. [Symmetry codes: (i) −x + 2, y + , −z + ; (ii) −x + 2, y − , −z + .] |
