The title dinuclear di-mu-oxo-bis[(1,4,8,11-tetraazacyclotetradecane-kappa(4)N)manganese(III,IV)] diperchlorate nitrate complex, Mn(2)O(2)(C(10)H(24)N(4))(2)(2)(NO(3)) or (cyclam)MnO(ClO(4))(2)(NO(3)), was self-assembled by the reaction of Mn(2+) with 1,4,8,11-tetraazacyclotetradecane in aqueous media. The structure of this compound consists of a centrosymmetric binuclear (cyclam)MnO unit, two perchlorate anions and one nitrate anion. While the low-temperature electron paramagnetic resonance spectra show a typical 16-line signal for a di-mu-oxo Mn(III)/Mn(IV) dimer, the magnetic susceptibility studies also confirm a characteristic antiferromagnetic coupling between the electronic spins of the Mn(IV) and Mn(III) ions.
标题为二核双-μ-氧-双[(1,4,8,11-四氮杂环十四烷-κ(4)N)锰(III,IV)]高氯酸硝酸盐配合物，Mn(2)O(2)(C(10)H(24)N(4))(2)(2)(NO(3))或(环胺)MnO(ClO(4))(2)(NO(3))，是通过Mn(2+)与1,4,8,11-四氮杂环十四烷在水介质中反应自组装而成。该化合物的结构由一个中心对称的双核(环胺)MnO单元、两个高氯酸根阴离子和一个硝酸根阴离子组成。虽然低温电子顺磁共振光谱显示出二-μ-氧Mn(III)/Mn(IV)二聚体典型的16线信号，但磁化率研究也证实了Mn(IV)和Mn(III)离子电子自旋之间存在特征性反铁磁耦合。
