Two complexes were obtained during the reactions of 6-amino-1-methyl-5-nitrosouracil (AMNU) and 6-methylamino-1-benzyl-5-nitrosouracil (MABNU) with cis-diaquadiamineplatinum(II) nitrate complex, cis-[Pt(NH3)2(H2O)2](NO3)2. The complexes were isolated in good yields as powdery precipitates. They were characterized through their elemental analysis, infrared, UV–vis, and 1H NMR spectroscopies as well
在6-氨基-1-甲基-5-硝基souracil(AMNU)和6-甲基氨基-1-苄基-5-硝基souracil(MABNU)与顺式-二二胺铂(II)硝酸盐络合物顺式[[]的反应中获得了两种配合物。Pt(NH 3)2(H 2 O)2 ](NO 3)2。以粉末状沉淀物的高收率分离出复合物。通过元素分析,红外,紫外可见和11 H NMR光谱学和热分析。所得结果表明,嘧啶碱基容易取代水配体,并以中性和离子形式分别以单齿配体与Pt(II)离子相互作用,成为配体AMNU和MABNU。环外氧原子是最可能的结合位点。在两种情况下都提出了方形平面结构,即顺式。筛选游离配体及其Pt(II)复合物的抗菌活性。
