| 中文摘要 | the solution structures of diamagnetic lanthanide (iii) complexes of dtpa-bin (ln = la, y, lu, sc) have been investigated by h-1 nmr, c-13 nmr and 2d nmr. for each complex, two or more species of asymmetric conformations with little distinction were identified at room temperature. and their solution structures vary with the radius of the central metals. nmr spectra support the hypothesis that sc3+ with smaller radius formed an eight-coordinated structure with dtpa-bin, la3+ with larger radius formed nine- or ten-coordinated structures with dtpa-bin, and y (dtpa-bin) and lu (dtpa-bin) had nine-coordinated solution structures. the solution structure of gd (dtpa-bin) was obtained from the similarity of radius between gd3+ and y3+, which is a nine-coordinated structure formed by three nitrogens, three acetate oxygens, two acetyl oxygens, one water molecule and a gadolinium(iii) cation. |
