Some new lead(II) complexes of the general formula Pb(L)2, where HL = Schiff bases derived from the condensation of isatin and chloroisatin with phenylalanine (HL1/HL4), isoleucine (HL2/HL5), and glycine (HL3/HL6), have been synthesized and characterized by elemental analysis, molar conductance, electronic, infrared, and multinuclear magnetic resonance (1H and 13C) studies. In all cases, the Pb atom
某些通式为Pb(L)2的新的铅(II)配合物,其中HL =异丁烯和氯异丁烯与苯丙氨酸(HL 1 / HL 4),异亮氨酸(HL 2 / HL 5)缩合得到的席夫碱合成了甘氨酸(HL 3 / HL 6),并通过元素分析,摩尔电导,电子,红外和多核磁共振(1 H和13C)研究。在所有情况下,Pb原子都处于四配位环境中,两个二齿去质子化的席夫碱通过氧和偶氮甲碱氮作为单阴离子配体结合。还对代表性化合物之一[Pb(L 3)2 ]进行了键长和键角的3D分子建模和分析,以证实所提出的结构。
