description

A novel rhenium(IV)–manganese(II) double salt of formula (NBu4)10[{ReCl4(ox)}3Mn]2[ReCl6] (1) (NBu4+ = tetra-n-butylammonium cation and ox2– = oxalate dianion) has been prepared through the simultaneous use of two different anionic ReIV complexes, namely, [ReCl4(ox)]2– and [ReCl6]2–, in the presence of MnII ion, the [ReCl6]2– anion playing a key role in the crystallization process. 1 has been magnetically characterized and its crystal structure determined by single-crystal X-ray diffraction. The study of the magnetic properties reveals the occurrence of intramolecular antiferromagnetic exchange between ReIV and MnII ions. Remarkably, 1 is the first reported example of ReIV salt based on two different anionic ReIV complexes.
