【摘要】：過渡金屬Schiff堿類配合物因其結(jié)構(gòu)的復(fù)雜多樣、獨(dú)特和新穎的性能,得到了大多科學(xué)家們的注意。這類化合物通常是由含有氨基(-NH_2)的化合物與醛或酮發(fā)生縮合反應(yīng)而得到的含有C=N基團(tuán)的化合物,其C=N上的N原子能夠提供一對孤對電子給大部分過渡金屬離子從而得到金屬配合物,而使其在化學(xué)分析、生物醫(yī)藥、農(nóng)藥、催化、超分子、分子磁性及材料科學(xué)等諸多領(lǐng)域具有著廣泛的用途。在本論文中,首先合成了4-氨基苯乙酮O-芐基肟;然后通過它與2-羥基萘甲醛和3,5二氯水楊醛縮合反應(yīng),合成了2種不同的氨基苯乙酮肟類化合物,它們分別為:1-(4-{[(2-羥萘基)次甲基]氨基}苯基)乙酮O-芐基羥氨肟配體(HL~1)、1-(4-{[(3,5-二氯-2-羥苯基)次甲基]氨基}苯基)乙酮O-芐基羥氨肟配體(HL~2);用2-氨基-3-羥基吡啶分別與合成的3-醛基-4-羥基香豆素和3,5二溴水楊醛反應(yīng),合成了2種不同的2-氨基-3-羥基吡啶類化合物,它們分別為:4-羥基-3-[(3-羥基-吡啶-2-亞氨基)]-苯并吡喃-2-酮配體(HL3)、2-[(3,5-二溴-2-羥基)-氨基]-吡啶-3-醇配體(HL~4)。通過自然放置揮發(fā)溶劑的方法,使得5個(gè)配合物單晶被培養(yǎng)出來,配合物單晶分別:[Cu(L~1)_2](1),[Ni(L~1)_2](2),[Mn4(L~2’)_2(μ3-OMe)_2(μ2-OMe)_2(Me OH)_2](3),[Ni2(L3)_2(D MF)_2](4),[Zn2(L~4)_2(H_2O)_2]·2DMF(5),對這4種配合物進(jìn)行了紅外、紫外、熒光等性質(zhì)表征,并且利用X-射線單晶結(jié)構(gòu)衍射法確定了它們的化學(xué)組成及空間結(jié)構(gòu)。其相關(guān)的晶體學(xué)數(shù)據(jù)為:配合物1:化學(xué)組成為C_(52)H_(42)CuN_4O_4,Mr=850.44,屬于Monoclinic,空間群I2/c,晶胞參數(shù):a=21.8573(13)?,b=5.8605(4)?,c=33.683(2)?,α=90.00°,β=97.428(5)°,γ=90.00°,Z=4,V=4278.4(5)?~3,R_1=0.0554,wR_2=0.1042;配合物2:化學(xué)組成為C_(52)H_(42)NiN_4O_4,Mr=845.60,屬于Triclinic,空間群P1,晶胞參數(shù):a=5.6602(6)?,b=10.585(2)?,c=18.053(3)?,α=76.312(17)°,β=89.215(11)°,γ=78.818(13)°,Z=1,V=1030.3(3)?~3,R_1=0.0866,wR_2=0.1353;配合物3:化學(xué)組成為C_(40)H_(40)Cl_8Mn_4O_(16),Mr=1280.08,屬于Triclinic,空間群P1,晶胞參數(shù):a=9.3045(13)?,b=11.792(3)?,c=12.408(3)?,α=70.12(2)°,β=75.412(16)°,γ=80.928(15)°,Z=1,V=1235.1(5)?~3,R_1=0.0823,wR_2=0.1922;配合物4:化學(xué)組成為C_(18)H_(15)N_3NiO_5,Mr=412.04,屬于Monoclinic,空間群P21/c,晶胞參數(shù):a=9.9121(4)?,b=14.1192(6)?,c=12.4016(5)?,α=90°,β=102.395(5)°,γ=90°,Z=4,V=1695.16(13)?~3,R_1=0.0361,wR_2=0.0815;配合物5:化學(xué)組成為C_(12)H_8Br_2N_2O_3Zn·C_3H_7NO,Mr=526.49,屬于Monoclinic,空間群P21/c,晶胞參數(shù):a=11.5966(6)?,b=13.9483(4)?,c=11.3506(6)?,α=90°,β=105.547(5)°,γ=90°,Z=4,V=1768.82(14)?~3,R_1=0.0533,wR_2=0.1330.
[Abstract]:Transition metal Schiff base complexes have attracted the attention of most scientists because of their complex and diverse structures, unique and novel properties.These compounds are usually compounds containing Con N groups, which are obtained by condensation of compounds containing amino acids and aldehydes or ketones.The N atom on its Con N can provide a pair of lone pairs of electrons to most transition metal ions to get metal complexes, which can be used in chemical analysis, biomedicine, pesticides, catalysis, supramolecular chemistry,Molecular magnetism and material science are widely used in many fields.In this thesis, 4-aminoacetophenone O-benzyl oxime was synthesized firstly, and then two kinds of aminoacetophenone oxime compounds were synthesized by condensation of 2-hydroxynaphthalene formaldehyde and 3o 5-dichloro-salicylic aldehyde.They are: 1-1-[[[2-hydroxynaphthyl) methylene] amino} phenyl] acetone] -benzylamine oxime ligand HL-1HYDROXYLHYDROXYL 4- {[CHLORON-2-HYDROXYLPHENYL] aminophenyl} phenyl) ethanone O- benzyl hydroxaminoxime ligand HL2; 2-amino-3-hydroxypyridine, respectively.Reaction with 3-Aldol -4-hydroxycoumarin and 3- (5-dibromo-salicylidene),Two kinds of 2-amino-3-hydroxypyridine compounds were synthesized. They are: 1 -4-hydroxy-3- [3-hydroxy-pyridine-2-imino] -benzopyran -2-one ligand HL-2- [tribromo-5-dibromo-2-hydroxypyridyl] -pyridin-3-ol ligand HL-4.閫氳繃鑷�鐒舵攧〗�鎸ュ彂婧跺墏鐨勬柟娉，
