在水杨醛与二元胺形成的Schiff碱与Mn盐的反应体系中分离出两个单核Mn化合 物，(salen)Mn(H_2O)Cl(1)和[(salpr)Mn(H_2O)_2]Cl(2)，并测定了结构。应用对 苯二甲酸在碱性条件下拉接两个单核Mn的Schiff碱配位单元，生成(salen)_2Mn_2 [μ-p-C_6H_4(COO)_2](H_2O)(CH_3OH)(3)并进行了结构表征。讨论了这些化合物 的红外及~1HNMR谱，揭示了Mn中心对配体信号的影响。

In the reaction system consisting of Mn salt and Schiff base obtained from salicylaldehyde and diamine, two mono-manganese complexes, (salen) Mn (H_2O) Cl (1) and [(salpr)Mn(H_2O)_2]Cl (2) were isolated and their crystal structures were determined. Di-manganese complex (salen)_2Mn_2[μ-p-C_6H_4(COO)_2]-(H_2O)(CH_3OH) (3) was prepared by using terephthalic acid which links both Mn/Schiff base coordination units under basic condition and was structurally characterized. The IR and ~1H NMR spectra were discussed to exhibit the influence of the Mn site on the spectral signals of the ligands.

Key words: MANGANESE COMPLEX, CRYSTAL STRUCTURE, SCHIFF BASE, salicylic aldehyde, IR, 1HNMR, STRUCTURE CHARACTERISTICS
