  • Coordination Compounds
    Complexes formed by a central metal cation bonded to surrounding ligands.
  • Ligands
    Molecules or ions that donate a pair of electrons to a central metal atom in a coordination complex.
  • Cation
    A positively charged ion, often a metal, in a coordination compound.
  • Anion
    A negatively charged ion that can act as a counterion in coordination compounds.
  • Neutral Ligands
    Ligands with no charge, such as NH3 or water, listed before anionic ligands in naming.
  • Anionic Ligands
    Negatively charged ligands, named with an 'o' suffix, like cyano or bromo.
  • Complex Ion
    A charged species consisting of a metal ion bonded to one or more ligands.
  • Counterion
    An ion that balances the charge of a complex ion in a coordination compound.
  • Roman Numerals
    Used to indicate the oxidation state of a transition metal with multiple charges.
  • Numerical Prefix
    Indicates the number of each type of ligand, such as di-, tri-, tetra-.
  • Alphabetical Order
    The sequence in which ligands are named in a complex, ignoring numerical prefixes.
  • Brackets
    Used to enclose the formula of a complex ion in a coordination compound.
  • Ferrate
    The name for an iron-containing anionic complex, derived from its Latin name.
  • Plumbate
    The name for a lead-containing anionic complex, derived from its Latin name.
  • Aqua
