Figure 2
The zigzag chain of hydrogen-bonded moieties in the crystal of 1 [view direction [001]; 30% probability ellipsoids; symmetry codes: (A) −x + , y − , z; (B) x, y + 1, z]. Features indicative for the mode of concatenation of the characteristic building blocks by hydrogen bonding are: (i) double hydrogen-bond donor and double (κO,κO′) hydrogen-bond acceptor functionality of the aqua ligand and dioxane moiety, respectively; (ii) almost equal strength of both hydrogen bonds; (iii) an approximatety linear arrangement of the dioxane O atoms and the two neighbouring water O atoms (e.g. O1, O3A, O2A and O1A); (iv) an approximately planar arrangement of B1, F1, O1, O2 and O3. |
