Bis(triethanolamine-N,O,O')zinc(II) disaccharinate

Y. Topcu, V. T. Yilmaz and C. Thöne

Abstract: The structure of the title complex, [Zn(C6H15NO3)2](C7H4NO3S)2, consists of a complex cation and two saccharinate (sac) anions. In the complex cation, the zinc(II) ion is octahedrally coordinated by two tridentate (N,O,O') triethanolamine (tea) ligands with a facial distribution. Two ethanol groups of each tea ligand form two five-membered chelate rings around the zinc(II) ion, while the third ethanol group remains uncoordinated. In addition to weak [pi]-[pi] interactions between the phenyl rings of neighbouring sac ions, H atoms of free and coordinated hydroxyl groups are involved in hydrogen bonding with amine N, carbonyl O and sulfonyl O atoms of the adjacent sac ions, forming a three-dimensional network.
