Double azido-bridged and mixed-bridged binuclear copper(II) and nickel(II) compounds with N,N,O-donor Schiff bases: Synthesis, structure, magnetic and DFT study
Abstract Two dinuclear complexes μ1,1-azido bridged [Cu(L1)(N3)]2 (1) and μ-phenoxo, μ1,1-azido bridged [Ni2(L2)2(μ1,1-N3)(N3) H2O] (2) bearing HL1 and HL2 as a blocking co-ligands produced by the 1:1 condensation of N-benzyl ethylenediamine with ortho-hydroxy acetophenone and N-methyl propanediamine with 3-methoxy salicylaldehyde respectively, have been synthesized and successfully characterized by elemental analyses, IR and electronic spectroscopy, single-crystal X-ray diffraction, variable temperature magnetic study and DFT studies. X-ray crystal structures of 1 reveal that the Cu(II) ion displays a five-coordinate square pyramidal coordination with a centro-symmetric μ1,1-azido bridging…
Azido bridged binuclear copper(ii) Schiff base compound: synthesis, structure and electrical properties
An azido bridged dinuclear complex [Cu(L−)(μ1,1N3)]2 (1) was synthesized by a 1 : 1 condensation of N-cyclohexyl-1,3-propanediamine and 5-bromosalicylaldehyde (HL). The complex was subsequently characterized based on elemental analyses, IR, single-crystal X-ray diffraction, a Hirshfeld study, FESEM, ESI-MS, powder XRD and also DFT studies successfully. The X-ray crystal structure of complex 1 revealed that the Cu(II) ion exhibited a definite five-coordinate square pyramidal coordination arrangement with a centro-symmetric μ 1,1-azido bridging in the end-on mode and formed a dimeric structure. The optical direct band gap of complex 1 was estimated to be 2.84 eV. The current–voltage character…
