| 摘要: 以二茂铁甲酸根FcCOO-(Fc=(η5-C5H5)Fe(η5-C5H4))为主要配体，合成了3个新的配合物[Na2Cd( μ3-η2-FcCOO-)2(μ2-η2-FcCOO-)2(CH3OH)2]n (1)、[Cd(phen)(FcCOO-)(η2-FcCOO)(H2O)](phen=邻菲咯啉) (2)、[Cd(Det)(η2-FcCOO-)(FcCOO-)](H2O)2(Det=二乙撑三胺) (3)。测定了配合物的晶体结构。配合物1为单斜晶系，C2/c空间群，二茂铁甲酸根采用μ3-η2-FcCOO-和μ2-η2-FcCOO-的配位方式将Cd2+和Na+连接成一维无限链状结构。配合物2和3均为单核结构，单斜晶系，P21/c空间群，二茂铁甲酸根都采用 FcCOO-和η2-FcCOO-的方式配位。2中phen以双齿螯合形式配位，水分子参与配位，中心镉离子配位数为6。3中Det以三齿螯合形式配位，中心镉离子配位数也为6，但水分子未参与配位。 |

| Abstract: Three new cadmium complexes with ferrocenemonocarboxylate FcCOO-(Fc=(η5-C5H5)Fe(η5-C5H4)) as main ligand, {[Na2Cd( μ3-η2-FcCOO-)2(μ2-η2-FcCOO-)2(CH3OH)2]n (1)、[Cd(phen)(FcCOO-)(η2-FcCOO)(H2O)](phen=1,10-phenanthroline) (2)、[Cd(Det)(η2-FcCOO-)(FcCOO-)](H2O)2(Det=Diethylenetriamine) (3)}, were synthesized and their crystal structures have been determined. Complex 1 crystallizes in monoclinic system, space group C2/c. The Cd2+ and Na+ ions were linked by ferrocenemonocarboxylate in coordination modes of μ3-η2-FcCOO- and μ2-η2-FcCOO- to form an one-dimensional infinite chain. Both complex 2 and 3 are mononuclear structure, crystallize in monoclinic system with space group P21/c. The ferrocenemonocarboxylate coordinates to central metal ion in the modes of FcCOO- and η2-FcCOO-. In 2, the phen coordinates in the way of chelating bidentate and the H2O molecule takes part in the coordination. The coordination number of cadmium ion is six. In 3, the Det coordinates in chelating tridentate mode. The coordination number of cadmium ion is also six, but the water molecule doesn′t involve in the coordination. CCDC: 1: 272940; 2: 272941; 3: 272942. |
