| 英文摘要 | 在水溶液中合成了三乙四胺六乙酸钆配合物:K_4[Gd_2(HTTHA)_2]14H_2O的单晶,并测定了其结构.晶体属单斜晶系,P2_1/n空间群.晶胞参数:a=1.1266(5)nm,b=2.5686(4)nm,c=2.2076(8)nm,β=102.50(3)°,V=6.237(6)nm~3,Z=4,D_c=1.812g/cm~3.配合物是双核分子.每个钆离子与来自同一个三乙四胺六乙酸的3个氮原子和4个羧基氧原子,来自另一个三乙四胺六乙酸的2个羧基氧原子配位,形成三冠三角棱柱型配位多面体.; The gadolinium complex with triethylenetetraaminehexaacetic acid (abbreviated as H(6)TTHA), K-4[Gd-2(HTTHA)(2)]. 14H(2)O was synthesized in aqueous solution, and its crystal structure was determined by X-ray diffraction method. The crystal is monoclinic, space group P2(1)/n, with a=1.1266(5) nm, b=2.5686(4) nm, c=2.2076 nm, beta=102.50(3)degrees, V=6.237 (6)nm(3), Z=4, D-c=1.812 g/cm(3). The complex is a binuclear molecule, each gadolinium ion is coordinated by three nitrogen atoms and four carboxyl oxygen atoms from one TTHA, and two carboxyl oxygen atoms from another TTHA, forming a coordination polyhedron of tricapped trigonal prism.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1997XT40700009&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 30; 07; 672-677; 55 |
