Pd(II) formamidine complexes formulated as [Pd(L 1−4 )Cl 2 ] where L = formamidine ligands, were synthesized and characterized using different tools, such as; elemental analyses, mass, infrared spectroscopy, magnetic susceptibility, thermal analysis and DFT calculations. The complexes are diamagnetic and the electronic spectral data showed the peaks due to square planar Pd(II) complexes. The optimized
摘要 二元 Pd(II) 甲脒配合物被合成并表征为 [Pd(L 1-4 )Cl 2 ],其中 L = 甲脒配体,使用不同的工具,例如;元素分析、质量、红外光谱、磁化率、热分析和 DFT 计算。配合物是抗磁性的,电子光谱数据显示出由于方形平面 Pd(II) 配合物引起的峰。配合物 (1–4) 的优化结构表明 Cl Pd Cl 和 N Pd N 键角在 83.89°–94.27° 范围内的扭曲方形平面几何形状。配合物的电子能(au)(-553.79至-763.92)和最高占据分子轨道(-0.223至-0.250)和最低未占据分子轨道能量(-0.091至-0.127)为负值表明稳定性的复合体。如偶极矩值 (6.50–15.71 Debye) 所示,复合物被极化。所有配合物均为中性、稳定且不吸湿。该复合物具有显着的细胞毒性,IC 50 (μM):0.0740 (MCF-7)、0.0074–0.0082
