trans-Diaquabis(2-pyridylethanol-N,O)nickel(II) disaccharinate

Abstract

The title complex, [ Ni( pyet)(2)( H2O)(2)]( sac)(2) ( sac(-) is the saccharinate anion, C7H4NO3S-, and pyet is 2- pyridylethanol, C7H9NO), is built of discrete sac(-) and [ Ni( H2O)(2)( pyet)(2)](2+) ions. The Co2+ ion sits on a centre of symmetry and exhibits a distorted octahedral geometry, formed by two bidentate pyet and two water molecules. The crystal structure is stabilized by hydrogen- bonding and weak aromatic pi - pi- stacking interactions between the planar sac(-) ions, forming a three-dimensional network.
