| Abstract: | 本論文以Schiff-bases、[M(CN)6]3-、N(CN)2-…等不同架橋基當作多芽配位基，加入了過渡金屬及鑭系金屬等多種不同金屬，合成具有多核之金屬錯合物，共得到了二個多核銅錯合物，二個一維鏈狀多核錯合物，及一個異雙核錯合物和單核銅錯合物…等六個金屬錯合物。
六個錯合物Complexes(1)~(6)分別為:
(1) [Cu6(L1)4]•2(ClO4)
(2) [Cu4(L2)4]•4H2O
(3) {Cr(CN)5(μ-CN)[(K2(H2O)(d-phen)3)(H2O)(K(d-phen)2)]•3H2O•(d-phen)}n
(4) {(μ1,3-O3)[MnⅢ(CN)4(μ-CN)2(MnⅡ(phen)2)2] •H2O}n
(5) [Ce(DMF)4(H2O)3(μ-CN)Cr(CN)5•H2O]
(6) [Cu(dcaOMe)2]
H3L1 : 【1,3-Bis(5-chlorosalicylideneamino)propan-2- ol】
H2L2 : 【2-(3-methoxy-salicylideneamino)-benzyl-alcohol】
phen : 1,10-Phenanthroline
d-phen : 4,7-dimethyl-1,10-phenanthroline
經由單晶結構的解析，錯合物之元素分析組成、紅外線光譜、EPR光譜及變溫磁化率(2 ~ 300 K)等測定，藉此了解各個錯合物其金屬間立體配位結構與磁性行為表現的關聯性，在磁性方面尚藉由最佳適模方式來探討其金屬間可能的磁交換作用來進行更深入的研究探討。
Abstract:
In the present thesis, we reported six metal complexes with polydentate ligands H3L1~ H2L2 and bridging ligand ( [M(CN)6]3- , N(CN)2- ). The molecular structures of these complexes have been determined by single-crystal X-ray diffraction method, and the magneto-structural correlations of these complexes are investigated :
(1) [Cu6(L1)4]•(ClO4)2
(2) [Cu4(L2)4]•4H2O
(3) {Cr(CN)5(μ-CN)[(K2(H2O)(d-phen)3)(H2O)(K(d-phen)2)]•3H2O•(d-phen)}n
(4) {(μ1,3-O3)[MnⅢ(CN)4(μ-CN)2(MnⅡ(phen)2)2] •H2O}n
(5) [Ce(DMF)4(H2O)3(μ-CN)Cr(CN)5•H2O]
(6) [Cu(dcaOMe)2]
H3L1 : 【1,3-Bis(5-chlorosalicylideneamino)propan-2- ol】
H2L2 : 【2-(3-methoxy-salicylideneamino)-benzyl-alcohol】
phen : 1,10-Phenanthroline
d-phen : 4,7-dimethyl-1,10-phenanthroline
The single-crystal X-ray studies shown that, the complexes (1)~(2) are polynuclear complexes, (3)~(4) are 1-Dimensional chain complexes, and (5) is a heterometallic complex while (6) is a mononuclear complex.
These complexes have been characterized by elemental analysis, IR spectra, and Variable-temperature ( 2 ~ 300 K ) magnetic susceptibility were measured. |
