Abstract
- A novel dinuclear nickel(II) complex Ni2(NO3)4(APTY)4 (1) (APTY = 1,5-dimethyl-2-phenyl-4-{[(1E)-pyridine-4-ylmethylene]amino}-1,2-dihydro-3H-pyrazol-3-one), was synthesized by solvothermal reaction of Ni(NO3)2 · 6H2O with APTY in methanol at 353 K. The structure consists of centrosymmetric dimers resulting from octahedrally coordinated Ni atoms bridged by APTY ligands. Weak intermolecular interactions (C-H ··· N, C-H ··· O hydrogen bonding, C-H ··· π and π-π stacking interactions) are responsible for a supramolecular assembly of molecules in the lattice. Magnetic measurements over 1.8-300 K show weak antiferromagnetic coupling between Ni(II) ions with J = 2.969 cm-1, g = 2.280, θ = -5.903. [ABSTRACT FROM AUTHOR]
