Bis(acesulfamato)tetraaquacobalt(II).

Area of Science:

• Inorganic Chemistry
• Crystallography
• Coordination Chemistry

Background:

• Acesulfame is a widely used artificial sweetener.
• Metal complexes of organic ligands are of interest for their diverse properties.
• The synthesis and structural characterization of novel metal complexes are crucial for understanding chemical bonding and material science.

Purpose of the Study:

• To synthesize and determine the crystal structure of the first acesulfame-metal complex.
• To investigate the coordination behavior of acesulfamate ligand with cobalt(II).
• To analyze the intermolecular interactions stabilizing the crystal lattice.

Main Methods:

• Single-crystal X-ray diffraction was used to determine the crystal structure.
• Spectroscopic methods were employed for characterization (details not provided in abstract).
• Hydrogen bonding analysis was performed based on the determined crystal structure.

Main Results:

• The crystal structure of tetraaquabis[6-methyl-1,2,3-oxathiazin-4(3H)-onato 2,2-dioxide-kappaN]cobalt(II), [Co(C4H4NO4S)2(H2O)4], was successfully determined.
• The cobalt(II) ion is coordinated by four water molecules and two acesulfamate ligands through their nitrogen atoms.
• The crystal lattice is stabilized by a network of intra- and intermolecular hydrogen bonds, forming a 3D structure.

Conclusions:

• This study reports the first example of an acesulfame-metal complex.
• The coordination geometry and hydrogen bonding network provide insights into the structural properties of acesulfamate complexes.
• The findings contribute to the understanding of coordination chemistry involving artificial sweeteners.
