Figure 4
A view of the mol­ecular packing down (a) the c axis in crystals of (II)[link] and (b) the b axis in crystals of (I). Dotted lines represent hydrogen-bonding inter­actions, some of which (shown in Fig. 3[link]) have been omitted for clarity. [Symmetry codes: (i) x + [{1\over 2}], −y + 1, z; (vi) −x, −y + 1, z + [{1\over 2}]; (xiii) x + 2, y + [{1\over 2}], −z + 1; (xiv) −x + 2, y − [{1\over 2}], −z + 1; (xv) −x + 1, y + [{1\over 2}], −z + 1; (xvi) −x + 1, y − [{1\over 2}], −z + 1.]
