| Popis: | 93 A series of dinuclear and teranuclear copper(Ⅱ) complexes (1)~(4) containing Schiff-base, derived from salicylaldehyde, 3-tert-butyl-2-hydroxybenzaldehyde, 3,5-di-tert-butyl-2-hydroxybenzaldehyde, and 1,3-diamino-2-propanol are reported. These dinuclear and teranuclear complexes are bridged by pyrazole,6-methoxypurine, dimethylmalonic acid, 1,4-phenylenediacetic acid. These complexes are: （1）〔Cu2(L1)(C3H3N2)〕 （2）〔Cu2(L1)2(C5H6O4)〕 （3）〔Cu2(L2)2(C10H8O4)〕 （4）〔Cu2(L3)(C6H5N4O)〕 L1：【 1,3-bis(3-tert-butylsalicylideneamino)propan-2- ol】； L2：【1,3-bis(salicylideneamino)propan-2- ol】； L3：【1,3-bis(3,5-di-tert-butylsalicylideneamino)propan-2- ol】 The complexes have been characterized by single crystal X-ray, elemental analysis, IR spectra,Variable-temperature ( 2 ~ 300K ) magnetic susceptibility,Theoretical studies (DFT) have been performed to understand magnetic behavior of these complexes. The reactive activities of copper(Ⅱ) complexes for catecholase-like also are investigated. |
