Abstract

In the crystal structure of the title compound [systematic name: diaquabis(6-methyl-2,2-dioxo-1,2,3-oxathiazin-4-olato-κO 4)bis(3-methylpyridine-κN)nickel(II)], [Ni(C<inf>4</inf>H <inf>4</inf>NO<inf>4</inf>S)<inf>2</inf>-(C<inf>6</inf>H<inf>7</inf>N) <inf>2</inf>(H<inf>2</inf>O)<inf>2</inf>], the NiII centre resides on a centre of symmetry and has a distorted octahedral geometry. The basal plane is formed by two carbonyl O atoms of two monodentate trans-oriented acesulfamate ligands and two trans aqua ligands. The axial positions in the octahedron are occupied by two N atoms of two trans pyridine ligands. Molecules are stacked in columns running along the a axis. There are π-π stacking interactions between the molecules in each column, with a distance of 3.623 (2) Å between the centroids of the pyridine rings. There are also O-H⋯O interactions between the columns. © 2007 International Union of Crystallography.
