Homework Help: Nomenclature Of Complex Ions

  1. Oct 15, 2007 #1
    1. The problem statement, all variables and given/known data
    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?

    2. Relevant 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.

    3. The attempt at a solution

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

    Is this answer and the equations correct? Thanks.
