K3[CoF6]

Postby Sarah Jeong 4F » Thu Dec 06, 2018 6:56 pm

Why do we not follow the alphabetic rule when we say that K3[CoF6] is "potassium hexafluorocobaltate(3)" rather than "potassium cobaltate(3)hexafluoro?"

I believe this is because Co is the transition metal cation and F is considered the ligand in this case.

the alphabetical rule only applies to the ligands attached to the transition metal. In general, the transition metal will always come after the ligands in the name.
