Figure 4
Part of the crystal packing of (II), illustrating the complex hydrogen-bond network. Hydrogen bonds are shown as dashed lines and H atoms not involved in hydrogen bonding have been omitted for clarity. Only the major parts of the disordered atoms of the propyl side chain (C16/C17) and of the ethanol solvent molecule (C19/C20/O6) are shown. 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 + , −y − , −z; (ii) x, y + 1, z; (iii) x − , −y − , −z.] |
