摘　　要：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(H2 O)Cl(1)和 [(salpr)Mn(H2 O) 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) 2 Mn2 [μ p C6H4 (COO) 2 ](H2 O) (CH3 OH) (3)并进行了结构表征 .讨论了这些化合物的红外及1HNMR谱 。In the reaction system consisting of Mn salt and Schiff base obtained from salicylaldehyde and diamine, two mono-manganese complexes, (salen)Mn(H2O)Cl (1) and [(salpr)Mn(H2O)(2)]Cl (2) were isolated and their crystal structures were determined. Di-manganese complex (salen)(2)Mn-2[mu-p-C6H4(COO)(2)]-(H2O) (CH3OH) (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 H-1 NMR spectra were discussed to exhibit the influence of the Mn site on the spectral signals of the ligands.
