ACTA CRYSTALLOGRAPHICA SECTION C-STRUCTURAL CHEMISTRY, vol.61, 2005 (SCI-Expanded)
The crystal structure of the first acesulfame - metal complex, namely tetraaquabis[6-methyl-1,2,3-oxathiazin-4(3H)-onato 2,2-dioxide-kappaN] cobalt(II), [Co(C4H4NO4S)(2)(H2O)(4)], is reported. The Co-II 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.
