  Nickel(II) and iron(II) mononuclear complexes with 1-methylimidazole-2-aldoximate: New building units for molecule-assembled magnetic materials

  摘要：

  A new class of mononuclear metal complexes with 1-methylimidazole-2-aldoximate (miao) has been synthesized and characterized: trans-NiII(Cl)(2)(Hmiao)(2) (1), trans-NiII(miao)(2)(py)(2) (2), NO-trans-NiII(miao)(2)(phen) (3), and NO-trans-FeII(mia0)2(phen) (4). The crystal structures of 2, 3, and 4 have been determined by single-crystal X-ray crystallography. Compound 1 having the protonated miao ligand (i.e., Hmiao) is a precursor for synthesizing 2 and 3. Compound 2 is an octahedral NiII complex surrounded by two miao bidentate ligands and two monodentate ligands of pyridine in a trans-arrangement. Compound 3 is a cis-type octahedral NiII complex with two miao ligands and a bidentate ligand of 1, 10-phenanthroline, in which the ligand arrangement around Nil I center is found in an NO-trans form. Compound 4 is an isostructural FeII derivative of 3. Compounds 1, 2, and 3 exhibit paramagnetic nature with an S = 1 spin and a positive zero-field splitting, among which it for 3 is overlapped with intermolecular ferromagnetic interaction (zJ/k(B) = +0.16 K). Compound 4 is diamagnetic due to the existence of low-spin FeII ion. (c) 2005 Elsevier B.V. All rights reserved.

  The NiII ion is coordinated to two ligands in bidentate mode through nitrogen atoms. Complex II has one unique HgII atom and forms a dimeric complex that contains two HgII atoms related by a crystallographic inversion center. In this complex, the oxime ligand is ligated to the metal ion in a monodentate fashion through the nitrogen atoms. On the basis of bond distances, this complex exhibits a distorted
