Figure 5
Part of the crystal structure of (II)[link], showing the formation of the centrosymmetric hexa­molecular R46(36) and dimeric R22(8) ring motifs, along with the tetra­molecular R44(29) ring motif. Hydrogen bonds are shown as dashed lines. Selected atoms of the mol­ecules present in the asymmetric unit are labelled, primarily to provide a key for the coding of the atoms. The hydrogen bonding of the water mol­ecule is not shown. For the sake of clarity, the unit-cell outline has been omitted, together with H atoms not involved in hydrogen bonding. [Symmetry codes: (i) x + 1, −y + [{3\over 2}], z + [{1\over 2}]; (ii) x, −y + [{3\over 2}], z + [{1\over 2}]; (iii) −x − 1, −y + 1, −z + 1; (iv) −x, y − [{1\over 2}], −z + [{3\over 2}].]
