| 摘要: 在不同条件下合成了[Co(phen)mXp]Y1·nH2O型配合物,(m=1,2;p=1,2;1=1-3;n=0-4;phen=邻菲绕啉；X=Cl-,H2O,酒石酸(tart),甘氨酸(gly),α-皮可林酸(pic).DL-两氨酸(ala),L-亮氨酸(leu),L-脯氨酸(pro);Y=Cl-,NO3-,ClO4-],并进行了元素分析,热重分析,电子光谱,红外光谱和磁化率测定,计算它们的10Dq和B值。X-ray单晶衍射实验证明：[Co(Phen)2(H2O)2](NO3)3·2H2O,[Co(Phen)2(gly)]Cl2·4H2O均为顺式结构。[Co(Phen)(ala)2]Cl·3H2O,[Co(Phen)(pro)2]ClO4·4/3H2O均为trans(N)结构。在[Co(phen)2X2]n+型配合物中,X反位的键长均长于顺位键长,其反位效应的顺序为：Cl->羧基,NH2>H2O. |

| Abstract: The mixed ligand coordination compounds, [Co(phen)mXp]Y1·nH2O (where m= 1, 2;P = 1, 2;1 = 1, 2, 3;phen=1, 10-phenanthroline;X=Cl-, H2O, CO32-, tartate, α-picolinic acid,glycinc, DL-alanine, L-leuline, L-prolinc;Y= Cl-, NO3, ClO4-), were synthesized in different.condition. Their structures were studied by elemental analysis, thermogravimctric analysis,UV-Vis spectra. infrared spectra, susccptibility and X-ray single crystal cxperimental. Their 10Dq, Racah parameters B and electron clound expansion parameters β were calculated and their single crystal experiment show [Co(phen)2(H2O)2](NO3)3·2H2O, [Co(phen)2,(gly)]Cl2·4H2O, [Co(phen)2,(ala)2]Cl·3H2O and [Co(phen)(pro)2]ClO4·4/ 3H2O are cis, cis, trans(N)and trans(N), respectively. The Co-N bond distances of trans to X atoms are slightly longerthan that of cis to X atoms in the [Co(phen)2X2]n+ complex. |
