| 英文摘要 | Nine Ln( III) complexes with a novel Schiff base derived from diglycolamine and benzoylacetone (BZDA) have been synthesized and characterized. They can be formulated as [Ln(2)(BZDA)(3)(NO3)(3)](NO3)(3). nH(2)O (Ln = La, Pr, Nd, Sm, n = 4; Ln = Gd, Tb, Er, Yb, Y, n = 7). Enamic form mechanism in this beta- diketone Schiff base and its complexes were suggested and proved by IR, UV and NMR methods. The C-13 spin-lattice relaxation time T-1 and the ratios of r((ci-Ln))/r((cj-Ln)) were measured by a 500 MHz NMR instrument for elucidating the formation of the stable six-membered chelate ring structure in these complexes. The EPR spectrum of the Gd(III) complex exhibits the "U" spectral feature and "zero field effect". On the basis of them, the crystal field strength and the local symmetry around Gd3+ in the complex have been discussed. |
