“…Its water-soluble sodium salt therefore is widely used as artificial sweetener for diabetics as well as an additive in dietetic products. Recently, it has also been used for ionic liquids [10]. The saccharinate anion has been shown to coordinate to Cr, Zn, V, Pb, Hg, Mn, Co, and the complexes [M(sacc) 2 (OH 2 ) 4 ] (M ¼ Cr, Zn) [11]; [V(sacc) 2 4 ] $ 2 py (py ¼ pyridine) [12]; [Pb(sacc) 2 ] $ H 2 O [13]; [HgCl(py)(sacc)] 2 [14]; [Mn(phen) 2 (sacc)(OH 2 )](sacc), [Co(bipy)2-(sacc)(OH 2 )](sacc) (phen ¼ phenanthroline, bipy ¼ bipyridine) [15]; [Zn(sacc) 2 [16] have been reported.…”
