A novel rhenium(IV)-manganese(II) double salt of formula (NBu4)(10)[{ReCl4(ox)}(3)Mnb[ReCl6] (1) (NBu4+ = tetra-n-butylammonium cation and ox(2-) = oxalate dianion) has been prepared through the simultaneous use of two different anionic Re-IV complexes, namely, [ReCl4(ox)](2-) and [ReCl6](2-), in the presence of Mn-II 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 Re-IV and Mn-II ions. Remarkably, 1 is the first reported example of Re-IV salt based on two different anionic Re-IV complexes.
