Why do the answers for b and d not include "ate" at the end of the transition metal so why isn't it "cobaltate"? The solution manual for some of them includes the "ate" like for letters a and c and then all of them include "ion" at the end. Why is this?
Hi, I posted some notes here at this link: viewtopic.php?f=157&t=38247&p=129743&hilit=coordination+compound&sid=05ea6f12f71e75b6ecc59a05bf7b6d6e#p129743. Essentially, if the overall complex has a positive charge, metal is same name as element (ex. Co in a complex cation is called cobalt, and Pt is called platinum (Fe would just be iron)). If the overall complex has a negative charge, metal ends with the suffix "-ate" (ex. Co in a complex anion is called cobaltate, and Pt is called platinate (Fe would be ferrate)).
