Abstract

A binuclear nickel(II) complex of [Ni₂(bispicen)₂(μ-N₃)₂](ClO ₄)₂ [bispicen = N,N′-bis (2-pyridylmethyl)ethylenediamine] has been synthesized and characterized by means of elemental analysis, IR and electronic spectra. The crystal structure was determined by single-crystal X-ray diffraction technology. The complex crystallizes in orthorhombic space group P2₁2₁2₁. The nickel(II) ion resides in a pseudo-octahedral environment with a cis - α configuration. The azido ligand bridges two Ni(II) ions in the μ-1,3 (end-to-end) mode, and unlike most polynuclear complexes with double μ-1,3-N₃ bridges, where the (N₃)₂ bridging moiety forms a plane, the two azido bridges in the present complex are non-coplanar and crossed at an angle of 49.7°. The temperature dependence of the magnetic susceptibility of the complex has been investigated and revealed an antiferromagnetic interaction between the two Ni(II) ions with the exchange integral J = -28.1 cm^-1(based on Ĥ = -2JŜ₁Ŝ₂).
