Two novel FeII–ReIVcompounds of general formula [FeII(DEA)6][ReIVX6] where DEA = diethylacetamide and X = Cl (1) and Br (2) have been prepared and magnetostructurally characterised. Complexes1and2are isomorphic ionic salts that crystallise in the trigonal crystal system with space groupR(−3). The rhenium(IV) ion in1and2is six-coordinate with six chloro (1) or bromo (2) ligands building a regular octahedral chromophore. The FeIIion is also six-coordinate, and bonded to six oxygen atoms from six DEA molecules. [FeII(DEA)6]2+cations and [ReIVX6]2−anions alternate in the crystal lattice of1and2generating supramolecular structures whose magnetic properties are dominated by the high anisotropy of the six-coordinate iron(II) and rhenium(IV) ions. Variable-temperature magnetic susceptibility data of1and2are well reproduced by a model of isolatedS= 2 (FeII) andS= 3/2 (ReIV) centres with high values of the local zero-field splitting.1and2are the first examples of hexahalorhenate(IV) salts incorporating FeIIcomplex cations to have been magnetostructurally investigated.
