  Synthesis, characterization, crystal structure, magnetic studies of a novel polymeric zig-zag chain copper (II) complex

  摘要：

  A single crystal of copper (II) complex (1) has been synthesized and its crystal structure has been determined by single crystal X-ray diffraction analysis and characterized by elemental analyses, IR spectroscopy, thermal analysis, H-1 NMR and C-13 NMR spectroscopy. The complex crystallizes in orthorombic space group Pnma, with unit cell dimensions a = 9.8944, b = 25.2972, c = 7.4457 angstrom, ss = 90 degrees. Structural analysis of (1) shows that the Schiff base ligand coordinates toward one metal atom in a pentadentate mode and each Cu atom is six-coordinated. The aliphatic oxygen atom of Schiff base ligand links the [CuL] moieties and creates polymeric zig-zag chain structure. In addition, magnetic susceptibilities for complex (1) have been measured over the temperature range 2-300 K and the magnetic parameters have been determined with fitting procedure. Magnetic measurements on (1) reveal the presence of antiferromagnetic exchange interactions between Cu(II) ions in the dimeric unit via bridging oxygen atoms of pentadentate Schiff base ligand.

  Recently, the dicopper(II) complexes [Cu2(L1)(3,5-prz)] (L1 = 1,3-bis(2-hydroxy-1-napthylideneamino)- propan-2-ol) (1) and [Cu2(L2)(3,5-prz)], (L2 = 1,3-bis(2-hydroxy-5-chlorosalicylideneamino)- propan-2-ol) (2) were reported. These compounds show antiferromagnetic behaviour (-2J: 444 cm-1 for 1 164 cm-1 for 2, and 472 cm-1 for 3). The strength of the super-exchange interaction (-2J) of 2 is much less

  A family of isostructural, hexanuclear lanthanide complexes [Ln(6)(L)(4)( mu(3)-OH)(4)(CH3OH)(2)(NO3)(2)] (Ln = Gd (1), Tb (2), Dy (3), Ho (4), Er (5), H3L = 1,3-bis(4-methoxysalicylideneamino)-2-propanol) were obtained by the reactions of Ln(NO3)(3) with the selective ligand. Complexes 1-5 were characterized by X-ray single crystal diffraction, IR spectra, and powder X-ray diffraction analyse. The molecule structure of these complexes contains a Ln(6)O(6) core ligated by two trinuclear subunits. Direct-current (dc) magnetic susceptibility studies reveal the antiferromagnetic interactions between Lanthanide ions. The in-phase (X') and out of -phase (X") signals have been observed below 10 K in complex 3, indicating slow relaxation of the magnetization. The deduced effective energy barrier (U-eff/k(B)) and relaxation time (tau(0)) are 6.17 K and =4.9 x 10(-5) s, respectively. (C) 2017 Elsevier Ltd. All rights reserved.
