Coordination Compound Naming!
I have 6 compounds to name. I named all 6, but please check my answer and if wrong, please explain why and how to do it. Thank you so much!
1. [Pt(NH3)4Cl2]SO4 - tetraamminedichloroplatinum (IV) sulfate
2. K3[Mo(CN)6F2] - potassium hexacyanodifluoromolybdenate (V)
3. K[Co(EDTA)] - potassium ethylenediaminetetraacetate cobaltate(III) Note: For the cobalt oxidations state, I calculated it to be +3 because EDTA has a charge of -4 and and K is +1. So, it needs to be +3 to neutral. However, my friends got +1 and I do not quite understand why and who is correct.
4. Co(NH3)3(NO2)3 - triamminetrinotrocobalt (III)
5. [Fe(en)3][IrCl6] - tris(ethylenediamine)iron (0) hexachloroiridiate (VI) Note: as you can see this is the one I need help with. I thought both complexes had to be neutral and since en is 0, Fe is 0. Cl is 6(-1) making Ir +6. But when it comes to naming Fe in a cation complex, is it just written as iron? In anionic form, I know it has to be ferrate.
6. Ca3[Ag(S2O4)2]2 - calcium bis(dithionate)aurate (I) Note: since dithionate is an anion in this complex, would the name change to dithionato?
Thank you so much!
