Abstract
Abstract Four new nickel(II) binuclear complexes have been synthesized and characterized, namely [N12(TCPHT A)(L)4](ClO4)2 (L denotes 1, 10-phenanthroline (phen), 5-niitro-l, 10-phertanthroline (NO2-phen), 2, 2′-bipyridyl (bpy) and 4, 4′-dimethyl-2, 2′-bipyridyl (Mezbpy), respectively), where TCPHTA is the tetrachlorophthalate dianion. Based on IR, elemental analyses and conductivity measurements, these complexes are proposed to have telrachlorophthalato-bridged structures consisting of two nickel(II) ions in which each nickel(II) ion has a distorted octahedral environment. The temperature dependance of the magnetic susceptibility for [N12(TCPHTA) (phen)4](CIO4)2 · H2O was measured over the range 4–300 K and the observed data were successfully simulated by an equation based on the spin Hamiltonian operator ( ). giving the exchange integral J = - 1.12 cm-1. This indicates weak antiferromagnetic spin exchange interaction between the metal ions.
