Abstract: | The asymmetric unit of the title compound, {Ni(C12H6N2O4)(H2O)3]·H2O}n, is composed of a lattice water molecule and a nickel(II) ion that is coordinated by three water molecules and the two N atoms of a 2,2′‐bipyridine‐3,3′‐dicarboxylate ligand. The twist of the 2,2′‐bipyridine‐3,3′‐dicarboxylate unit and the coordination of one carboxylate group to a symmetry‐related NiII atom generate a helical chain that runs along the b axis. Intrahelical hydrogen bonds participate in controlling the orientation of the helices, and both right‐handed and left‐handed helices are connected by interhelical hydrogen bonds into two‐dimensional sheets. |
