  Influence of the secondary coordination sphere on the physical properties of mononuclear copper(II) complexes and their catalytic activity on the oxidation of 3,5-di-tert-butylcatechol

  摘要：

  Three mononuclear copper(II) complexes (C1-C3) containing the ligand 2-(2-aminomethyl)pyridine (aep) and some modifications of it were designed to get insights on the influence of pendant second sphere groups (thiophene and benzene) on their physicochemical and catalytic properties. Complexes C1-C3 were synthesized reacting copper(II) chloride with the precursor ligand LP1, N-(2-(pyridin-2-yl) ethylidene)-1-(thiophen-2-yl)methanamine, and" the ligands L2, 2-(pyridin-2-y1)-N-(thiophen-2-y-Imethy)ethanamine, and 13, N-benzyl-2-(pyridin-2-yl)ethanamine, respectively. The complexes were isolated and characterized by several methods. Single crystal X-ray crystallographic studies revealed that Cl results from the cleavage of the Schiff base PL1, yielding the distorted square planar copper(II) complex coordinated to one molecule of aep and two chloride ions, which have been already published. All complexes present the same coordination sphere; C2 and C3 have also pendant arms. These groups induce singular crystal packing by different intermolecular interactions, which correlates with the decomposition temperatures of the complexes. In addition, electronic, redox and catalytic properties are also influenced. Complex C3 is the most efficient in the oxidation of 3,5-di-tert-butylcatechol (3,5-DTBC) and presents catalytic efficiency of 72.9 L mor(-1) s(-1). It is 4.5 and 11-fold greater than those determined for Cl and C2, respectively. Complexes reaction orders of 0.70 +/- 0.04 for Cl, 1.6 +/- 0.1 for C2 and 0.913 +/- 0.002 for C3 indicate different catalytic species in each case, with mechanisms involving more than one active species for Cl and C2. Different mechanisms can explain the catalytic behavior of these complexes. (C) 2017 Elsevier Ltd. All rights reserved.

  The single-crystal X-ray structures of two new linear trinuclear copper(II) complexes of 3,5-pyrazoledicarboxylic acid (H3L) are reported, viz. [Cu-3(L)(2)(Me(2)en)(2)(H2O)(2)].(H2O)(8) (1) and [Cu-3(L)(2)(MeOH)(6)(H2O)(4)](2), with Me(2)en is N,N-dimethylethylenediamine. Both complexes are trinuclear and have been obtained from a precursor ligand, through copper-induced amide hydrolysis. In 1, the central copper ion is in a distorted square-planar environment and the two outer copper ions are in a distorted square-pyramidal environment. All three copper ions in 2 are six-coordinated in an elongated octahedral environment. A weak, broad EPR signal centered around g = 3.5. indicative for an S = 3/2 state, is observed and confirms both complexes to be trinuclear. Magnetic susceptibility measurements of 1 and 2 from 4 to 300 K indicate a weak anti-ferromagnetic exchange coupling, with J values of - 15 and - 19 cm - 1, respectively.
