| 英文摘要 | 在水溶液中合成了三乙四胺六乙酸(H6ttha)钆单核配合物(NH4)2[Gd(Hdttha)].6H2O,获得了单晶,并测定了其结构.晶体属单斜晶系,P21/c空间群.晶胞参数a=1.0400(4)nm,b=1.2761(4)nm,c=2.3132(4)nm,β=90.89(3)°,V=3.070(2)nm3,Z=4,Dc=1.709g/cm3.R1=0.0394,F(000)=1612.配合物是单核分子,每个钆离子与来自同一个三乙四胺六乙酸的4个氮原子和5个羧基氧原子配位,配位数为9,形成单帽四方反棱柱型配位多面体.; The gadolinium complex with triethylenetetraaminehexaacetic acid (abbreviated as H(6)ttha), (NH4)(2) [Gd(Httha)] . 6H(2)O was synthesized in aqueous solution, and its crystal structure was determined by X-ray four-cycle diffraction method. The crystal is monoclinic, space group P2(1)/c, with a = 1.040 0(4) nm, b = 1.276 1(4) nm, c = 2.313 2(4) nm, beta = 90.89(3)degrees, V = 3.070(2) nm(3), Z = 4, D-c = 1.709 g/cm(3). The complex was a mononuclear molecule, each gadolinium ion is coordinated by four nitrogen atoms and five carboxyl oxygen atoms from one Httha, forming a coordination polyhedron of mono capped square antiprism.; 国家攀登计划; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000079044500003&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 16; 2; 176-180; 20 |
