Question:
Before the structures of octahedral complexes were established, various means were used to explain the fact that d-metal ions could bind to a greater number of ligands than expected on the basis of their charges. For example, Co3+ can bind to six ligands, not just three. An early theory attempted to explain this behavior by postulating that once three ligands had attached to a metal ion of charge +3, the others bonded to the attached ligands, forming chains of ligands. Thus, the compound [Co(NH3)6]Cl3, which we now know to have an octahedral structure, would have been described as Co(NH3ONH3OCl)3. Show how the chain theory is not consistent with at least two properties of coordination compounds.
