Abstract
The title complex, [Co(pyet)2(H2O)2](sac)2 (sac− is the saccharinate anion, C7H4NO3S−, and pyet is 2-pyridylethanol, C7H9NO) contains sac− ions and [Co(H2O)2(pyet)2]2+ cations, in which the Co2+ ion lies on a centre of symmetry and is octahedrally coordinated by two water and two neutral pyet molecules, which act as N- and O-donor bidentate ligands forming two symmetrically-related six-membered chelate rings. The crystal packing is determined by hydrogen bonding, as well as weak sac−–sac− π–π-stacking interactions, resulting in a three-dimensional network.
