Summary:By slow diffusion of pyridine (py) into an aqueous solution containing the respective metal salt and acetylenedicarboxylic acid (H ADC), single crystals of coordination polymers of composition [M (H O) (py) ADC] with M = Zn (1) and Cd (2) were obtained. The crystal structures consist of octahedral M units, which are connected to chains via acetylenedicarboxylate dianions. Hydrogen bonds between O atoms of the dianions and of the water molecules lead to the formation of layers perpendicular to [010]. The structure is further held together by weak aromatic stacking interactions between the pyridine ligands.
