  • Nomenclature for Coordination Compounds

    Solution: potassium is the cation and the complex ion is the anion. Since there are 4 K + binding with a complex ion, the charge on the complex ion must be -4. Since each ligand carries 1 charge, the oxidation number of Fe must be +2. The common name of this compound is potassium ferrocyanide

  • Coordination Complexes and Ligands

    Coordination Complexes. Coordination compounds, such as the FeCl 4-ion and CrCl 3 6 NH 3, are called such because they contain ions or molecules linked, or coordinated, to a transition metal.They are also known as complex ions or coordination complexes because they are Lewis acid-base complexes. The ions or molecules that bind to transition-metal ions to form these complexes are called ligands ...
