Figure 5
A partial packing diagram for (II), showing extracellular molecules, depicting the ribbon-like pattern generated by the N—H⋯O and N—H⋯N hydrogen bonds (dashed lines). 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. Atom O2iii lies exactly behind atom O2i. [Symmetry codes: (i) −x + 1, y − , −z + ; (ii) −x, y + , −z + ; (iii) −x + 1, y + , −z + .] |
