naming sequence

Postby George_Zhu » Wed Jul 24, 2019 4:30 pm

What is the naming sequence when naming coordinating compound, which means how each atoms or elements are ranged in name of the coordinating compound?

so we name the ligand first, then the transition metal cation (with its oxidation state as Roman numeral), then the anions
In the ligand naming, we name it in the alphabetical order.
for [Co(NH3)5Cl]Cl, amine starts with a, chlorine starts with c, so we name amine first. so it's pentaaminechlorocobalt(II)chloride

1)always name the cation before the anion.
2)Name the ligands first, in alphabetical order, and then name the metal atom or ion. Note: The metal atom or ion is written before the ligands in the chemical formula.
3)After naming the ligands, name the central metal. If the complex ion is a cation, the metal is named the same as the element.
4)To name a neutral complex molecule, follow the rules of naming a complex cation.Remember: Name the cation BEFORE the anion.

1) If there is a cation (i.e K) write it first as its own word and you don’t need to take into account it’s charge
2) start with the ligands and put them in alphabetical order
3) find the oxidation number of the metal
4) out the whole complex in brackets and then if the complex is an ion write the suffix -ate at the end of the central metal
5) If the complex is attached to an anion write it at the end
