Structure,spectra and reactivity of terbutaline-metal (Ⅱ) complexes(特布他林金属(Ⅱ)配合物的结构、光谱及反应活性)
用密度泛函理论B3LYP方法,在6 - 311 + G(d,p)基组水平上,计算并分析了瘦肉精代表性分子特布他林(L)与8种常见的金属离子M(II)形成的配合物ML(M=Mg,Ca,Mn,Fe,Ni,Co,Cu,Zn)的几何构型、紫外-可见吸收光谱和反应活性的异同.配合物的结合能以及自然键轨道分析显示,L能与M(II)离子结合成稳定的配合物,N,O原子的孤对电子和金属M的空轨道间相互作用对配合物的稳定性贡献较大.含时密度泛函结果表明,除ZnL基本不变外,其余7种ML分子的紫外吸收光谱峰均较其前体L有较大的红移.密度泛函活性指数显示,形成ML后的反应活泼性均要强于L单体.能量分解分析表明,静电效...
