  摘要：

  Two complexes of formulas [Ni(IM-Melmz)(2)(SCN)(2)]center dot CH3CH2OH (1) and [Mn(IM-Melmz)(2)(SCN)(2)]-3H2O (2), where IM-Melmz=2-(5-Methylimidazol-4-yl)-4,4,5,5-tetramethyl-2-imidazoline-1-oxyl, have been synthesized and characterized by single-crystal X-ray diffraction. The X-ray analysis demonstrates that IM-Melmz ligand is coordinated to metal ion with the kappa(2) N(Melmz), O(IM) mode to avoid steric hindrance with the methyl group in complex. In the solid state, the complexes 1 and 2 are linked by intermolecular hydrogen bonds, leading to two-dimensional structure. The variable-temperature magnetic susceptibility of both compounds suggests that the metal ions and radicals are ferromagnetically coupled with J = 2.78 and 1.11 cm(-1) for complexes I and 2, respectively.

  Two new copper(II) compounds with imino nitroxide radicals [Cu(IM-MeImz)2 · (SCN)] 0.5[Cu(SCN)4] (1) and [Cu(IM-MeImz)2 · (SCN)]ClO4 · H2O (2) (IM-meImz = 2-(5-methylimidazol-4-yl)-4,4,5,5-tetramethyl-2-imidazoline-1-oxyl) have been synthesized and characterized structurally and magnetically. X-ray analysis demonstrates that complex 1 contains CuII ions in both square-pyramidal and square planar coordination
