    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

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

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

    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
