A homotrinuclear complex of [NiDHDD]Cl2 (2), is formed with Ni(II) chloride and a heterotrinuclear complex of this ligand with Cu(II) chloride has been synthesized. The complexes [M(NiDHDD)2]Cl4 have been characterized on the basis of elemental analyses, magnetic susceptibility measurements, conductivity measurements, IR and electronic spectral studies. The trinuclear Ni(II) and Cu(II) complexes of the vic‐dioxime ligand [NiDHDD]Cl2 (2), have a M:ligand ratio of 1:2 and the ligand coordinates only through the N,N atoms, as do most vicinal dioximes.

Based on elemental analyses, magnetic moments at room‐temperature and molar conductivity measurements, spectroscopic (electronic and IR spectra) studies, it is proposed that these complexes have PMTA‐bridged structures and consist of two iron(II) ions in a distorted octahedral environment. The variable‐temperature magnetic susceptibilities (4–300 K) of the complexes [Fe2(PMTA)(Ph2phen)4] (1) and [Fe2(PMTA)(Me2phen)4] (2) were measured and studied in detail. The magnetic analysis was carried out by means of a least‐square method to the observed data with the susceptibility equation derived from the spin Hamiltonian operator, Ĥ = −2JŜ 1 Ŝ 2, giving the exchange integrals J = −0.96 cm−1 for (1) and J = −0.85 cm−1 for (2).
