✦ Synopsis

The title complex, Ni(pyet) 2 (H 2 O) 2 2 (sac À is the saccharinate anion, C 7 H 4 NO 3 S À , and pyet is 2-pyridylethanol, C 7 H 9 NO), is built of discrete sac À and [Ni(H 2 O) 2 (pyet) 2 ] 2+ ions. The Co 2+ 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 %±%-stacking interactions between the planar sac À ions, forming a threedimensional network.
