The synthesis of a symmetric,octadentate(N 6O 2) ligand [N,N,N ′N ′ tetrakis (2 ′ bonzimidazoly1 methy1) 1.4 diethyene amino] glycol ether (EGTB) and one containing manganese (Ⅱ) dinuclear complex [Mn 2EGTB (μ OAc) 2](OAC) (ClO 4)·2CH 3OH are reported.Ligand EGTB is characterized by 1 HNMR,UV Vis,IR spectrum.The elemetal analyses,UV Vis,molar conductivity,middle and far IR,activity of the complex have been studied.Its coordination glometry may be close to octahedral or distorted octahedral.This complex is probably a good struc...
