Cation vs. Anion Transition Metal

Postby Nick Lewis 4F » Sat Dec 07, 2019 8:13 pm

For example, on 9C.1, the transition metal is named cobalt for part B, but it is cobaltate for part C. How do you know which name to use? if the complex is anionic, do you name the transition metal + -ate or was this just a coincidence? Sorry, i dont remember what the rule for naming coord. compound transition metals in cations vs anions

If the coordination complex has an overall negative charge then you add an -ate at the end of the transition metal. If the coordination complex is positive you keep the name of the metal the same.

if the overall charge of the coordination complex is not 0 (so positive or negative charge) then -ate is added to the end of the metal ion

The suffix -ate is added to the metal when the complex is anionic. So if the overall charge of the complex is negative like it was in Part C, the name of cobalt became cobaltate.
