Hey there... I have a couple of queries about stability of transition metal complexes. I've been scouring the textbook and the internet but I'm not getting any closer to finding the answers, I'm not sure if I'm missing something really simple...
- Compare the stability of NH3 and ethylenediamine (en) complex ion of Ni2+ and with Co2+
-- for this I currently can only suggest that en will be a more stable complex with both metals because it's bidentate, it's also a stronger ligand on the spectrochemical series...
--Compare the stability of NH3 and en complex ion of Co3+ and Co2+
--Larger electrostatic attration with Co3+? .. although both ligands are neutral
--Which of the following complex ions is most stable?
Cu(NH3)42+ or Co(NH3)62+
Cu(tar)34- or Co(tar)34-
Any help would be greatly appreciated, thanks!
