二聚[Mn 2（saltmen）2（H2O）2]2+阳离子之间的反应（与saltmen=N，N′-（1，1，2，2-tetramethylethylene）bis（水杨醛亚胺）二价阴离子）和[Cr（CN）6]3−阴离子导致分离出二维层状络合物，[{Mn（saltmen）}4Cr（CN）6] ClO 4（1），其晶体结构已被确定，并提出了五聚氰桥CrMn 4单元组装成扩展层通过盐苯氧Mn-桥。详细的磁性测量及其分析表明，这些层具有亚铁磁性组织，Mn（III）和Cr（III）离子之间通过氰化物桥进行反铁磁性交换耦合（J/kB=−7（1）K），Mn（III）离子之间通过苯氧桥进行铁磁性相互作用。化合物1在TC= 5 K时表现出玻璃态亚铁磁有序。磁结构的讨论1和三个类似的二维系统的开发，解释在氰桥锰（III）-铬（III）的情况下观察到的反铁磁耦合。
Reaction between the dimeric [Mn2(saltmen)2(H2O)2]2+cations (with saltmen=N,N′-(1,1,2,2-tetramethylethylene)bis(salicylideneiminato) dianion) and [Cr(CN)6]3−anions results in the isolation of a 2D layered complex, [{Mn(saltmen)}4Cr(CN)6]ClO4(1), whose crystal structure has been determined and presents pentameric cyanido-bridged CrMn4units assembled into extended layers through saltmen phenoxo Mn–Mn bridges. Detailed magnetic measurements and their analysis show that the layers have a ferrimagnetic organization with antiferromagnetic exchange coupling (J/kB=−7(1)K) between Mn(III) and Cr(III) ions through cyanide bridges and ferromagnetic interaction between Mn(III) ions through phenoxo bridges. Compound 1 displays a glassy ferrimagnetic ordering with TC=5K. Magneto-structural discussions for 1 and three similar 2D systems are developed that explain the antiferromagnetic coupling observed in the cyanido-bridged Mn(III)–Cr(III) cases.
