Abstract
- Five novel trinuclear nickel(II) clusters were successfully synthesized, namely Ni<subscript>3</subscript>(fshz)<subscript>2</subscript>(L)<subscript>4</subscript>·n(sol) (H<subscript>3</subscript>fshz = N-formylsalicylhydrazide; L = pyridine, n = 0, 1; L = 4-methylpyridine, n = 1, sol = CH<subscript>3</subscript>CN, 2; L = 4-ethylpyridine, n = 2, sol = CH<subscript>3</subscript>OH, 3; L = 4-vinylpyridine, n = 1, sol = CH<subscript>3</subscript>OH, 4; and L = 2,6-pyridinedimethanol, n = 2, sol = CH<subscript>3</subscript>OH, 5). Single-crystal X-ray diffraction revealed that the metallic skeletons of 1–5 were built by three Ni(II) ions, two fshz<superscript>3−</superscript> units, and four auxiliary ligands. The coordination geometry of the Ni(II) ions in 1–5 are followed in two modes: square-planar and/or octahedral. Magnetic studies showed that 1–5 displayed intermolecular antiferromagnetic behavior and all the square-planar Ni(II) ions were diamagnetic as certified. Moreover, 1–4 presented easy-axis anisotropy with D = −4.02, −5.31, −4.82, and −3.65 cm<superscript>−1</superscript>, respectively, while 5 presented easy-plane anisotropy (D = 11.06 cm<superscript>−1</superscript>) due to the different coordination mode.
