A novel 4 · 82 CdII network constructed from helical motif: Incorporating alternate left- and right-hand helical water chains

A novel 2D 4 · 82 CdII network with alternating heterochiral motif was reported, which is extended to 3D through π–π stacking. Interestingly, 1D hydrophilic tunnel of 3D architecture, providing potential helical hydrogen-bonded identification sites, acts as a template for the formation of the alternate left- and right-handed 1D helical water chains. The compound exhibits intense photoluminescence at room temperature.
