Abstract: The title complexes [M(sac)₂(mpy)₂] [sac is saccharinate (C₇H₄NO₃S) and mpy is 2-pyridylmethanol (C₆H₇NO)], with M = Zn^II and Cd^II, are isostructural and consist of neutral molecules. The Zn^II or Cd^II cations are octahedrally coordinated by the two neutral mpy and two anionic sac ligands. The mpy ligand acts as a bidentate donor through the amine N and hydroxyl O atoms. The sac ligands exhibit an ambidentate coordination behaviour; one is N-coordinated and the other is O-coordinated within the same coordination octahedron. The crystal packing is determined by C-HO-type hydrogen bonding, as well as by weak py-py and sac-sac aromatic [bold pi] --stacking interactions.

Formula: [Zn(C₇H₄NO₃S)₂(C₆H₇NO)₂] and [Cd(C₇H₄NO₃S)₂(C₆H₇NO)₂]
