The synthesis, crystal structure and magnetic properties of the non-transition metals; Cd(II), Zn(II), Hg(II), Mg(II) and the transition metals; Co(II), Ni(II), Cu(II) complexes with 2-(4-pyridyl)-4,4,5,5- tetramethylimidazolinyl-1-oxy-3-oxide ( NITpPy) are presented. The compounds of free radical NITpPy, HgCl/sub 2/ (NITpPy), and Zn(acac)/sub 2/(NITpPy) crystallize in the same monoclinic system of space group C2/c. The magnetic properties of the temperature-dependent magnetic susceptibility of NITpPy and its metal complexes are discussed according to the Heisenberg model. A weak ferromagnetic coupling in NITpPy and a weak antiferromagnetic coupling in the metal complexes have been revealed.
