  Formation of an unusual copper(II) complex from the degradation of a novel tricopper(II) carbohydrazone complex

  摘要：

  An unusual copper(II) complex [Cu(L-1a)(2)Cl-2] CH3OH center dot H2O center dot H3O+Cl- (1a) was isolated from a solution of a novel tricopper(II) complex [Cu-3(HL1)Cl-2]Cl-3 center dot 2H(2)O (1) in methanol. where L-1a is 3-(2-pyridyl)triazolo [1,5-a]-pyridine, and characterized with single crystal X-ray diffraction study. The tricopper(II) complex of potential ligand 1,5-bis(di-2-pyridyl ketone) carbohydrazone (H2L1) was synthesized and physicochemically characterized, while the formation of the complex la was followed by time-dependant monitoring of the UV-visible spectra. which reveals degradation of ligand backbone as intensity loss of bands corresponding to O -> Cu(II) charge transfer.

  Ten new copper(II) complexes of five potential bisthiocarbohydrazone and biscarbohydrazone ligands were synthesized and physico-chemically characterized. The spectral and magnetic studies of compounds are consistent with the formation of asymmetric di-, tri- or tetranuclear copper(II) complexes of deprotonated forms of respective ligands. The variable temperature magnetic susceptibility measurements

  合成了五个潜在的双硫代碳carb和双碳carb配体的十个新的铜（II）配合物，并进行了物理化学表征。化合物的光谱和磁性研究与相应配体去质子化形式的不对称二核，三核或四核铜（II）配合物的形成是一致的。所有配合物的可变温度磁化率测量结果表明，Cu（II）中心之间存在反铁磁相互作用，与非常宽的粉末EPR光谱一致。但是，发现冷冻溶液EPR光谱研究与固态磁研究相矛盾，这表明络合物在溶液中不是很稳定。发现与MALDI MS结果一致的复合物可能碎裂。

  Yb) into square [2 × 2] grid-like arrays has been readily effected using simple, symmetric ditopic ligands based on a carbohydrazone core. The metal ions are connected via single atom bridges (e.g., μ2-Ohydrazone, μ2-OH, μ2-OMe, μ2-1,1-N3–, μ4-O), depending on reaction conditions. The Gd(III)4 examples exhibit intramolecular antiferromagnetic exchange (−J < 0.11 cm–1), and in one Dy(III)4 example,

  We synthesized an Fe(II) [2 × 2] molecular grid with pyridyl-substituted bis-terdentate ligands. The molecular grid showed abrupt spin crossover between fully high-spin and fully low-spin states in a narrow temperature width of ∼10 K. The spin crossover event also included a first-order structural phase transition, in which the dielectric constant jumped atypically toward a low-spin state.

  Four novel molecular square grids were achieved by self-assembly using the flexible ligands bis(di-2-pyridyl ketone) thiocarbohydrazone (H2L1), bis(quinoline-2-carbaldehyde) thiocarbohydrazone (H2L2), bis(di-2-pyridyl ketone) carbohydrazone (H2L3) and bis(2-benzoylpyridine) carbohydrazone (H2L4). Three complexes were given a general formula of [Ni(HL)](4)[PF6](4)center dot nH(2)O and one [Ni-2(HL2)L-2](2)(PF6)(2)center dot 7H(2)O. The MALDI-MS spectra reveal the formation of tetranuclear molecular squares. The square grid of the Ni(II) centers in all the complexes were organized by deprotonated ligands. The complex [Ni(HL1)(4)[PF6](4)center dot 11H(2)O crystallized as [Ni(HL1)](4)(PF6)(4)center dot 0.5CH(3)CH(2)OH center dot 2.8H(2)O and X-ray study revealed octahedral geometries around the Ni(II) centers. Variable temperature magnetic studies suggest intramolecular antiferromagnetic coupling between the Ni(II) electrons by a super exchange mechanism through intervening sulfur/oxygen atoms.
