Abstract
[M(saccharinato)2(H2O)4] (M = Cu2+, Ni2+, Co2+) react with nicotinamide to form mixed ligand complexes, [Cu(saccharinato)2(nicotinamide)(H2O)]⋅(H2O) (1) and [M(nicotinamide)2(H2O)4]⋅(saccharinate)2 (2: M = Ni2+; 3: M = Co2+), and their crystal structures have been determined by X-ray diffraction. In 1, the Cu2+ atom in an octahedral configuration is coordinated by two monodentate saccharinato ligands in the trans arrangement through the deprotonated ring nitrogens, by two bidentate nicotinamide ligands, one through the pyridyl ring nitrogen and the other through the amide oxygen, and by a water molecule, thus forming a nicotinamide-bridged one-dimensional extended structure. In the isomorphous complexes 2 and 3, the octahedral metal atom, which rides on a crystallographic center of symmetry, is coordinated by two monodentate nicotinamide ligands through the ring nitrogens and four water molecules to form a discrete [M(nicotinamide)2(H2O)4]2 + structural unit, which captures up and down two saccharinate ions, each through three hydrogen bonds: two hydrogen bonds between two water ligands and the ring N and the carbonyl O atoms and one between the amide N of the nicotinamide ligand and the carbonyl O.
