The low energy (thialene)Fe2(CO)6 structure has an η4,η4-thialene ligand bonded to two Fe(CO)3 units. The low-energy (thialene)Fe2(CO)5 structure has an η5,η3 thialene ligand bonded to an Fe2(CO)5 unit. Sulfur is not involved in ligand-metal bonding.

Very High

The lowest energy C4F8Fe(CO)4 structure is not the experimentally known ferracyclopentane complex but instead isomeric (perfluorobutene)iron tetracarbonyls. However, activation energies for the fluorine shifts required to form the latter isomers are very high. The lowest energy (C4F8)2Fe2(CO)n (n = 7, 6) structures have bridging perfluorocarbene and terminal perfluoroolefin ligands.

The potential accessibility of Fe2S(CO)n derivatives with 1:2 sulfur to iron ratios by the decarboxylation of iron carbonyl thionyls has led to their investigation using density functional theory. The lowest energy Fe2S(CO)n (n = 8, 7, 6) structures are predicted to be singlet structures with all terminal CO groups, a bridging sulfur atom, and a formal Fe–Fe single bond of length ∼2.5 Å. The Fe−S distances in these structures shorten from ∼2.3 to ∼2.1 Å as CO groups are lost, suggesting an increase in the formal Fe−S bond orders. The thermochemistry of CO dissociation suggests that both Fe2S(CO)8 and Fe2S(CO)7 are viable synthetic objectives. A similar density functional theory study of Fe2S2(CO)n derivatives (n = 7, 6, 5) finds the experimentally known Fe2S2(CO)7 structure with a bridging S2CO group and the Fe2S2(CO)6 structure with a bridging disulfide ligand to be the lowest energy structures by substantial margins of ∼17 and ∼21 kcal/mol, respectively. The low-energy structures for the unsaturated Fe2S2(CO)5 are derived from the low-energy Fe2S2(CO)6 structures by loss of a CO group in various ways with relatively little change in the underlying Fe2S2 framework.
