Abstract:
The reaction of Na2Fe(CO)4 with an excess of MnCl2 in tetra-hydro-furan (THF) produced {Fe2Mn(C4H8O)2Na2(C4H8O)5(CO)8] 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 inter-actions forming a polymeric (two-dimensional) structure in the crystal. One of the THF mol-ecules was modeled with the carbon atoms being statistically disordered.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
