Abstract

A supramolecular cation of (m-FAni+)(tst-DCH[18]crown-6), where m-FAni+ and tst-DCH[18]crown-6 denote m-fluoroanilinium and trans-syn-trans-dicyclohexano[18]crown-6, respectively, was introduced into a ferromagnetic {[MnIICrIII(oxalate)3]} layer to obtain a stable organic-inorganic hybridized crystal. The crystal structure of (m-FAni+)(tst-DCH[18]crown-6){[MnIICrIII(oxalate)3]} was constructed by alternate stacking of a two-dimensional honeycomb layer of {[MnIICrIII(oxalate)3]} and the supramolecular cations. Cyclohexyl moieties of tst-DCH[18]crown-6 penetrated the pores of the honeycomb layers, excluding solvent molecules in the crystal. The anionic layers showed ferromagnetic order of MnII and CrIII ions with S = 5/2 and S = 3/2 spins, respectively, at 5.5 K. Although the m-FAni+ showed disorder with respect to 180° rotation of the aryl ring, no significant anomaly was observed in the dielectric response, suggesting that the disorder is static.
