Antiferromagnetic coupling through cyano-bridge and H-bonds in [MnIII(3-OMesalophen)(H2O)2]2[MnIII(3-OMesalophen)(H2O)] [WV(CN)8] · 2H2O

A novel heterospin system [MnIII(3-OMesalophen)(H2O)2]2[MnIII(3-OMesalophen)(H2O)] [WV(CN)8] · 2H2O consists of Mn6IIIW2V distinguishable structural and magnetic units due to the presence of cyano-bridged anionic MnIIIWV dimers and bis-μ-aqua-bridged dimers of [Mn(3-OMesalophen)(H2O)2]+ cations linked by H-bonds and π-π stacking interactions; it exhibits the strong antiferromagnetic coupling through the single cyano bridge and significant AF couplings through the hydrogen bonds.
