2,6-二乙酰吡啶双缩萃甲酰肼(DAPBH)的过渡金属配合物的研究已见诸文献, 它的稀土盐的配合物仅有La(DAPBH)(NO3)3的十一配位分子结构的简报。考虑到镧系收缩的影响, 从镧到镥, 离子的配位空间减少和水合能增加, 它们的配合物将有不同的配位结构, 因此, 本文合成了部份稀土硝酸盐的配合物, 并对镱的配合物进行了单晶结构分析。

LnL(NO3)3.nH2O (Ln = La, Ce, Pr, n = 0, L = 2,6-diacetylpyridinebis(benzoylhydrazone); Ln = Ho, Er, Yb, n = 2) were synthesized and characterized by elemental analyses, IR spectra and elec. conductance. The crystal structure of the Yb complex was determine by x-ray diffraction. It crystd. in the monoclinic space group P21/c, a 9.570(1), b 23.367(4), c 13.853(2) ? b 109.15(1)? Z = 4, R = 0.027. The coordination no. of Yb3+ is 9.
