Ethanedioate

Wondered if it is required to put the -charge on O in the complex ion diagram

E.g. [Cr(C2O4)2(H2o)2]-

only asking this cuz according to textbook we don't need to put the charge on p212-chem textbook OCR


Someone please clarify

I wouldn't, I'd just write the overall charge after the second square bracket :smile:

Just out of interest, is this a real ion - the chromium only has 3 coordinate bonds instead of the standard 6.

The ethandioate ion is bidentate...

Ahh - is that '2' supposed to be subscript? :colondollar:

Even still, there are only 5 bonds, unless there are 2 waters?

5 valent complexes are really not very rare, what matters is the number of electrons donated rather than the number of ligands.

Never come across specific 5 valent complexes at A level before, sort of forgot they existed :redface:

I have no idea what you are talking about Ive written it as subscript!


nah jkk I just edited it :smile:
