Synthesis, crystal structure, and magnetic properties of a phenoxo-bridged dinuclear nickel(II) complex
A new dinuclear nickel complex, [ [image omitted](H1.5L)2](ClO4) · 2CH3OH · H2O (1) (H3L = 1,3-bis(salicylamino)-2-propanol), was synthesized and characterized by single-crystal X-ray diffraction, IR spectra, elemental analysis, and magnetic measurements. In contrast
to commonly observed alcoholic oxygen bridges in previously reported dinuclear complexes, single-crystal X-ray studies reveal that the H3L is highly distorted and links two NiII through the phenoxo oxygens of the ligands forming a [Ni2O2] core. The remarkable distortion of the ligand brings
the two non-bridging phenol groups from different ligands close to share one hydrogen, keeping charge neutrality of the complex. Magnetic studies indicate that an overall antiferromagnetic interaction is operative between the metal centers.
