Synthesis And Characterization Of Bidentate-coordinate Cobalt(Ⅱ) Compounds With Schiff Bases Containing Adamantyl Group

In this thesis,ten Schiff bases with adamantane group and the corresponding Schiff base complexes were synthesized.Melting point,IR,UV,thermogravimetry and elemental analysis were used to characterize these compounds.Nine complexes were analyzed by X-ray single crystal diffraction.The compounds structures were deduced.Work are enclosed as following:(1)Ten Schiff bases and their corresponding cobalt(II)complexes were obtained from cobalt(II)chloride hexahydrate and amantadine or rimantadine.The Schiff bases and the complexes were characterized by IR,UV,thermogravimetry and elemental analysis.(2)The crystal structures of complexes 1～6,8,9 and 10 were revealed.1:Dark red,monoclinic,space group P21/c;cell parameters:a = 16.2327(9)A,b=11.1334(4)A,c = 21.1201(12)A,a = 900,β=94.5860°,γ=900°,Z = 4,V=3574.3(3)A3,F(000)= 2205,R1=0.0927,ωR2 = 0.3201.2:Dark red,monoclinic,space group P21/c;cell parameters:a = 15.9951(9)A,b=11.0527(6)A,c = 22.7596(9)A,a = 90°,β=129.747(3)°,γ = 90°,Z = 4,V=3093.7(3)A3,F(000)= 1332,R1=0.0332,ωR2= 0.1001.3:Dark red,orthorhombic,space group Pbca;cell parameters:a= 11.1571(5)A,b = 20.5588(17)A,c=27.1509(11)A,a = 90°,β＝90°,γ=900°,Z = 4,V= 6227.8(6)A3,F(000)= 7878,R1=0.0750,ωR2 = 0.2405.4:Dark red,monoclinic,space group P21/c;cell parameters:a = 9.9166(9)A,b=9.9166(9)A,c = 13.8680(13)A,a = 900°,β = 107.475(2)°,γ=90°,Z = 4,V =3423.6(5)A3,F(000)= 1580,R1 = 0.0463,ωR2= 0.1433.5:Red,monoclinic,space group P21/c;cell parameters:a = 18.0156(17)A,b =10.8696(8)A,c = 18.8924(19)A,a = 90°,β=114.459(4)°,γ = 90°,Z = 4,V =3367.5(5)A3,F(000)= 1372,R1 = 0.0665,ωR2= 0.2114.6:Dark red,Triclinic,space group P 1;cell parameters:a = 8.9917(5)A,b =10.5130(7)A,c = 10.7186(5)A,a = 79.486(5),β=78.782(4),γ=75.477(5),Z=1,V=952.53(9)A3,F(000)= 385,R1 = 0.0452,ωR2= 0.1202.8:Bright red,monoclinic,space group P21/c;cell parameters:a = 9.2609(3)A,b=19.2802(5)A,c = 21.3356(6)A,a = 90°,β= 98.987(3)°,γ= 90°,Z = 4,V =3762.75(19)A3,F(000)= 2310,R1= 0.0562,ωR2= 0.1898.9:Bright red,monoclinic,space group P21/c;cell parameters:a = 9.3452(6)A,b=19.3896(2)A,c = 21.2518(17)A,a = 90°,β = 99.125(6),y = 90°,Z = 4,V =3802.1(5)A3,F(000)= 4032,R1= 0.0713,ωR2= 0.2183.10:Bright red,orthorhombic,space group Pbcn;cell parameters:a = 10.9176(18)A,b=13.088(2)A,c = 25.228(4)A,a = 900°,β= 90°,γ= 90°,Z= 4,V= 3604.8(10)A3,F(000)= 1500,R1=0.0557,ωR2 = 0.1523.
