1see ma very first post... i meant d same............
Colours in complexes are decided by the constituents of the coordination sphere, right? So why do K4[Fe(CN)6] and Fe2[Fe(CN)6] differ in colour though coordination sphere is intact?

11Yes, this is the reason, the Oxidation number of the metal ion is different and that is the deciding factor...........
11If that's the deciding factor, then in my q deciding factor is the same. Then why Colour change?
11K4[Fe(CN)6] and Fe2[Fe(CN)6]
here the coordination spheres are different...........
they are not same.
K4[Fe(CN)6] is actually K4[Fe(CN)6]4-
and Fe2[Fe(CN)6] is Fe2[Fe(CN)6]6-
so the colours are different........
got it.........

11Counter ions do not belong nor contribute to the properties exhibited by the coordination sphere
1sunil............ gr8 yaar........... kept full stop fr this..........
1cmon sunil i m with ani dont u know
its[Fe(CN)6]4- only
iron outside is Fe2+
33Ohhhhh
Thats enough!!
Now i think its enough as everyone now knows that their color are different and I don't think this will be asked anywhere expect FIITJEE AITS :P.....
Perhaps this is among other exceptions of Chemistry and we should accept it as this..
It doesn't make a sense to waste our time on a single question...as the concept (whichever will be involved) will help in no other questions other than this..
1leave d co sphere now.. they r similar... put dat out of ur brain....
ox state for d counter ions r different..............
so color differs...
bye....
ba bye...
ba ba bye...............
no more cross questions..............
askin cross question is an offence..........
1yup priyam i said it long ago dat ans to it is
dat its exceotion bt then ani says wats the reason for this exception waaaaaaahhhhhh......
1vishal.. cool.. then i explained ani abt wat is exception............
11Ok. if no one wants to reply then don't reply. Thread is closed! Thanx to all for (not) helping me. Byeee :)
1if u say very sentimentally, think dat u ll get it??????????????????

33Whatever the thread may be closed here but it will never be closed in our hearts ...
:P :P :P :P
Hope its not over philosophy :P
1priyammmmmmmmmmmmmmmmmmm ............ cant control my emotions...............
11Aragorn, iron outside the coordination sphere is Fe3+ and not Fe2+ coz Fe22+[Fe(CN)6]4- doesn't exit.. I've checked it.......
