2-(pyrimidin-2-ylamino)naphthalene-1,4-dione (L), has been synthesized by the reaction of 2-aminopyrimidine with 2-hydroxy-1,4-napthoquinone. Reaction of the ligand with Ni(II), Co(II), Mn(II) and Zn(II) acetate gave the corresponding metal complexes which were characterized by spectroscopic techniques, (infrared, electronic), elemental analysis, room-temperature magnetometry, conductance measurements and t
摘要 通过 2-氨基嘧啶与 2-羟基-1,4-萘醌反应合成了基于嘧啶的配体 2-(嘧啶-2-基氨基)萘-1,4-二酮 (L)。配体与 Ni(II)、Co(II)、Mn(II) 和 Zn(II) 醋酸盐反应得到相应的金属配合物,通过光谱技术(红外、电子)、元素分析、室温磁力测定法对其进行表征、电导测量和热重-差示扫描量热 (TG-DSC) 分析。复合物的室温磁数据和电子光谱测量结果证明了 4 坐标正方形平面/四面体几何形状。获得的热分析值表明是一水合物配合物。化合物的抗菌筛选显示出温和到非常好的结果。Mn(II) 配合物在 11.5-29 mm 范围内表现出最好的结果。使用密度泛函理论进一步讨论了配合物的电子、结构和光谱特性。分子对接研究显示与药物靶标具有显着的结合亲和力,并且金属配合物具有用作药物的潜力。
