A chiral Cu II dinuclear complex [Cu 2 ( L ‐shis) 2 ] · 4H 2 O (H 2 shis = N ‐salicylidenylhistidine) has been synthesized. The dinuclear units are assembled into a 3D hydrogen‐bonded supramolecular structure with 1D chiral channels through hydrogen bonds between imidazole N–H groups and carboxylate oxygen atoms. 1D left‐handed helical water chains in an AABB fashion, anchored through weak hydrogen‐bonding interactions with the host complex, are embodied in the chiral channels. X‐ray powder diffraction shows the porous structure is destroyed when the lattice water molecules are removed thermally from the channels. (© Wiley‐VCH Verlag GmbH & Co.
