Crystal structure of HESNAH. (a) Coordination polymer chains propagate along the b axis, giving rise to a 2D network through [PhO⋯H⋯PhO]− hydrogen bonds along the crystallographic bc plane. (b) Packing of 2D hydrogen-bonding networks in a way that (c) HES moieties self-assemble into cyclic dimers through pairs of PhOH⋯PhO− hydrogen bonds (motif I). |
