Bis(Acesulfamato)tetraaquacobalt(II)

Abstract

The crystal structure of the first acesulfame-metal complex, namely tetraaquabis[6-methyl-1,2,3-oxathiazin-4(3H)-onato 2,2-dioxide-κN] cobalt(II), [Co(C<inf>4</inf>H<inf>4</inf>NO<inf>4</inf>S)<inf>2</inf>(H <inf>2</inf>O)<inf>4</inf>], is reported. The CoII ion resides on a twofold axis and is coordinated by four aqua ligands defining the basal plane and by two monodentate acesulfamate ligands, via their ring N atoms, in the axial positions. Two intra- and three intermolecular hydrogen-bonding interactions stabilize the crystal structure and form an infinite three-dimensional lattice. © 2005 International Union of Crystallography.
