Figure 4
Part of the crystal packing of (I)[link], showing the zigzag hydrogen-bonded chain. 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 code: (i) −x + 1, y − [{1\over 2}], −z + [{3\over 2}].]
