Abstract
Treatment of Mn(OAc)2·4H2O with 3 equiv. HN(iPr2PO)2 in the presence of nBu4NCl in acetonitrile resulted in isolation of a tetranuclear {Mn III3 MnIV} complex [Mn4(μ3-O)3(μ3-Cl)(μ-OAc)3{N(iPr2PO)2}3]·0.5C6H14 (1·0.5C6H14), and a dinuclear {MnIIMnIII} complex [Mn2{N(iPr2PO)2}{μ2,η3-(iPrPO2)NH(iPr2PO)}2{η2-(iPrPO2)NH(iPr2PO)}2]·0.25AcOH (2·0.25AcOH) with bis(diisopropylphosphinyl)imide ligands. The solid-state structures of two complexes have been established by single-crystal X-ray crystallography. The tetranuclear complex 1 belongs to a family of {Mn III3 MnIVO3X} single-molecule magnets (SMMs) with effective energy barrier of 14.3 K by some further magnetic characterizations.
Graphical Abstract
A [Mn III3 MnIVO3Cl]-core-based [Mn4(μ3-O)3(μ3-Cl)(OAc)3{N(iPr2PO)2}3] complex with single-molecule magnet (SMM) behaviour was prepared and structurally characterized, exhibiting slow magnetization relaxation under zero applied dc field with τ0 = 9.0 × 10−7 s and relaxation barrier Ueff = 14.3 K.
