Seventeen new palladium(II) complexes of general formulaes PdCl2L, PdCl(LH− 1)(solvent) and PdCl2(PPh3)2L containing pyrimidine ligands derived from 6-amino-5-nitrosouracil and violuric acid have been prepared and characterized by elemental analysis, IR and NMR (1H and 13C) methods and, two of them, PdCl(DANUH− 1)(CH3CN)]·½H2O and [PdCl(2MeOANUH− 1)(CH3CN)] by X-ray single-crystal diffraction (DANU:
制备了十七种新的通式为PdCl 2 L,PdCl(LH -1)(溶剂)和PdCl 2(PPh 3)2 L的钯(II)配合物,其中含有衍生自6-氨基-5-亚硝基尿嘧啶和紫尿酸的嘧啶基通过元素分析,红外光谱和NMR(1 H和13 C)的方法和,其中的两个,的PdCl(DANUH - 1)(CH 3 CN)]·½H 2 O和[的PdCl(2MeOANUH - 1)(CH 3 CN)]通过X射线单晶衍射(DANU:6-氨基-1,3-二甲基-5-亚硝基尿嘧啶; 2MeOANU:6-氨基-2-甲氧基-5-亚硝基-3 H-嘧啶-4-一)。在具有不同超分子排列的两种化合物中,钯周围的配位环境几乎为正方形平面。当配体以中性形式以及单去质子化的配体中的N5和N6原子起作用时,晶体学和光谱数据与通过N5和O4原子的双齿配位模式一致。已经测试了该复合物对人神经母细胞瘤(NB69)和人神经胶质瘤(U373-MG)细
