What Are Common Mistakes in Naming Complex Ions?

Click For Summary
Common mistakes in naming complex ions often stem from confusion over the order of naming ligands and the oxidation state of the central ion. The correct approach involves naming negative ligands first, followed by neutral ligands, and then the central metal ion, which should include its oxidation state in Roman numerals. For example, [HgCl4]2- is correctly named tetrachloromercurate(II). Additionally, when the complex ion carries a negative charge, the suffix -ate should be added to the metal's name. Understanding these rules is crucial for accurate naming of complex ions.

Homework Statement


I'm having trouble with naming complex ions. My textbook has given me a few rules but the examples they give seem to contradict them. These are all the rules I know, can someone tell me if they are right and if I am missing any?


Homework Equations


Start naming with negative ligands then neutral and then the central ion using roman numerals such as di, tri, tetra, penta, and hexa.
Write in parantheses the oxidation of the central ion.
If the complex ion is negatively charged add the suffix -ate.


The Attempt at a Solution



So [HgCl4]2- should be tetrachloromercurate(II)

Is this answer and the equations correct? Thanks.
