【摘要】 <正> 邻羟基苄胺—O,N,N—三乙酸(o-Hydroxylbenzylamine-O,N,N—Triaceticacid)简称HBATA(见图)是一种既含有氨羧酸又含有醚氧羧酸二种配位基团的配位剂。在报告(Ⅰ)首次合成了HBATA,测得其与碱土金属和钴(Ⅱ)、镍(Ⅱ)等配合物的稳定常数。报告(Ⅱ)中表明HBATA为五齿配体。为了进一步确定HBATA与一些金属离子的配位性能,尤其是其中醚氧原子的配位作用,作者将制得的钴(Ⅱ)与HBATA更多还原

【Abstract】 The single crystal structure of Co(Ⅱ) complex of HBATA were determined on an Enraf-Nonius CAD 4 diffractometer, The space group of Co(Ⅱ) complex (Co[Co L·7H2O]2, L = C13H12NO73-) is P21:a with a = 11.836, b = 9.535, c= 18.399 A ,β = 91.86°, The Co(Ⅱ) ion was revealed by direct method, The other atoms were located from difference Fourier syntheses. Refinement was carried out by the full-matrix least-squares.The structure was refined to final R value of 0.044. The investigation confirms that the Co(Ⅱ) in this complex is six-coordinated with distorted octahedron configuration. The ether oxygen atom of HBATA is also coordinated to the central metal ion.更多还原
