The two new metal‐organic coordination frameworks [Ni 2 (pydc) 2 (4,4′‐bpy)(H 2 O) 4 ] n · 0.5 n (4,4′‐bpy)2H 2 O ( 1 ) and [Ni 2 (pydc) 2 (2,2′‐bpy) 2 (H 2 O) 2 ] n · 2 n H 2 O ( 2 ) (H 2 pydc = pyridine‐3,4‐dicarboxylic acid; bpy = bipyridine) have been synthesised under hydrothermal conditions and characterised by single‐crystal X‐ray diffraction analysis. The structure of 1 contains parallel rectangular channels that accommodate large 4,4′‐bpy guests while that of 2 contains vertical channels coordinated to 2,2′‐bpy ligands. Their magnetic analyses show that they exhibit different magnetic interactions. The red shifts of the peak in their emission spectra relative to those of the the free ligands could be attributable to the metal–ligand coordination. (© Wiley‐VCH Verlag GmbH & Co.
