Two coordination polymers [Hg2Cl4L·2­(DMF)]n, 1, and [Hg2Br4L·2­(DMF)]n, 2, where L is the N,N′-(1,2-diphenylethane-1,2-diyl)­diisonicotinamide ligand, have been synthesized and characterized. X-ray single crystal diffraction reveals that both coordination polymers are isostructural and that mercury adopts square based pyramid coordination geometry. Our results show that interplay between the coordination of the carbonyl group and π···π interaction of adjacent pyridine rings leads to the formation of 2D structures.
