Crystal structure of HESNA·H2O. (a) and (b) Bilayered 2D coordination networks propagate along the crystallographic bc plane and are cross-linked by hydrogen bonds between H2O molecules and HES− anions along the a axis. (c) Cyclic dimers of HES− form through pairs of PhOH⋯PhO− hydrogen bonds (motif I) which exist throughout the 2D coordination networks. HES− anions are shown in red. |
