Abstract:	本論文以水楊醛和氨基化合物以Schiff-base的方式合成配位基，再與錳形成錯合物，合成了三個錯合物，而第四個錯合物則為3,5-DTBC脫水再與錳形成錯合物，以下為所得四個錯合物: (1)[Mn(L1)(C6Br4O2)] (2)[Mn2(L2)2] (3)[Mn(L3)] (4)[Mn(3,5-DTBC)4] L1: 2-{(E)-[2-(2-aminoethylamino)ethylimino]methyl}-4-bromophenol L2: N,N,-bis(5-bromosalicylidene)-ethane-1,2-diamine L3: N,N,-bis(5-chlorosalicylidene)-ethane-1,2-diamine 3,5-DTBC = 3,5-di-tert-butylbenzene-catechol 除了就單晶結構上鍵結特性探討外，其粉末之SQUID變溫磁化率測定，都遵循Curie-Weiss Law，唯低溫部份χT隨溫度下降而降低，解釋為錳(Ⅲ)之軸對稱電子自旋相互作用(D)。另外就此類錯合物和H2O2反應有催化活性及化學動力學的探討。 In this thesis , the following complexes have been prepared from manganese complexes with Schiff-base and catecholate ligands : (1)[Mn(L1)(C6Br4O2)] (2)[Mn2(L2)2] (3)[Mn(L3)] (4)[Mn(3,5-DTBC)4] L1: 2-{(E)-[2-(2-aminoethylamino)ethylimino]methyl}-4-bromophenol L2: N,N,-bis(5-bromosalicylidene)-ethane-1,2-diamine L3: N,N,-bis(5-chlorosalicylidene)-ethane-1,2-diamine 3,5-DTBC = 3,5-di-tert-butylbenzene-catechol Temperature dependence of maganetic susceptibilities of these complexes were measured by SQUID magnetometer , showing the axial field symmetry of spin-spin interaction (D) of Manganese (Ⅲ) ion in octahedral distorted environments . All complexes exhibit catalase activities for the disproportionation of H2O2 into H2O and O2 (H2O2 catalase activity).
