  Magnetostructural correlations and catecholase-like activities of μ-alkoxo-μ-carboxylato double bridged dinuclear and tetranuclear copper(II) complexes

  摘要：

  Two mu-alkoxo-mu-carboxylato bridged dinuclear copper(II) complexes, [Cu-2(L-1)(mu-HCO2)] (1) ((H3L1 = 1,3-bis(5-bromosalicylideneamino)-2-propanol)), [Cu-2(L-2)(mu-HCO2)] (.) dmf (2) (H3L2 = 1,3-bis(3,5-chlorosalicylideneamino-2-propanol)), and two mu-alkoxo-p-dicarboxylato doubly bridged tetranuclear copper(II) complexes, [{Cu-2(L-3)}(2)(mu-O2CCH2(CH3)(2)-CO2) (.) 5H(2)O (.) 3CH(3)OH (3) ((H3L3 = 1,3-bis(salicylid-deneamino)-2-propanol)) and [{Cu-2(L-3)}(2)(mu- O2CCH2-C6H4-CH2CO2)] (.) 2H(2)O (4) have been prepared and characterized. The single crystal X-ray analysis shows that the structures of complexes 1 and 2 are dimeric with two adjacent copper(II) atoms bridged by mu-alkoxo-mu-carboxylato ligands with the (CuCu)-Cu-... distances and Cu-O(alkoxo)-Cu angles are 3.511 angstrom and 132.85 degrees for 1, 3.517 angstrom and 131.7 degrees for 2, respectively. Complexes 3 and 4 consist of mu-alkoxo-mu-dicarboxylato doubly bridged tetranuclear Cu(11) complexes with mean Cu-Cu distances and Cu-O-Cu angles of 3.158 angstrom and 108.05 degrees for 3 and 3.081 angstrom and 104.76 degrees for 4, respectively. Magnetic measurements reveal that I and 2 are strong antiferromagnetically coupled with 2J = -156 and -152 cm-1, respectively, while 3 and 4 exhibit ferromagnetic coupling with 2J = 86 and 155.2 cm(-1), respectively. The 2J values of 1-4 are linearly correlated to the Cu-O-Cu angles. Dependence of the pH at 25 degrees C on the reaction rate of oxidation of 3,4-di-tert-butylcatechol (3,5-dtbc) to the corresponding quinone catalyzed by 1-4 was studied. Complexes 1-4 exhibit high catecholase-like activity at pH 9.0 and 25 degrees C for oxidation of 3,5-di-tertbutylcatechol. (c) 2006 Elsevier B.V. All rights reserved.
