Poly[octa­carbonyl­heptakis­(tetra­hydro­furan)­diironmanganesedisodium(2 Mn—Fe)]

ABSTRACT: The title compound is a xenophilic transition-metal cluster with short iron–manganese bonds of 2.6274 (10) and 2.6294 (10) Å. The complex forms a polymeric (two-dimensional) structure through isocarbonyl linkages between the sodium cations and the Fe(CO)4 fragments of the cluster. The reaction of Na2Fe(CO)4 with an excess of MnCl2 in tetra­hydro­furan (THF) produced {Fe2Mn(C4H8O)2Na2(C4H8O)5(CO)8]n or C36H56Fe2MnNa2O15. The compound is a xenophilic dianion with short iron–manganese bond lengths of 2.6274 (10) and 2.6294 (10) Å. The sodium cations of the dianion are coordinated to THF ligands and have isocarbonyl inter­actions forming a polymeric (two-dimensional) structure in the crystal. One of the THF mol­ecules was modeled with the carbon atoms being statistically disordered.
