11Can u explain in more understandable terms? Or atleast tell where this exten..... comes into this question or how it explains it, please.
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?

1umm .. forget that .. see d- d transition state of Fe & K .. give e- config of K & Fe .. u have NCERT txtbk of class 12 ?
11Anyway in this case both are counter ions. So do they have any interactions wit the ligands in the coordination sphere?
1@ mallika how can u apply hyperconjugation here
u hav now interested me in this topic
1well i hav heard this phrrase extended hyperconjugation
bt i dont know where iwill try to search it & giv u a nice ans
:D
1was linking it to oximes lol .. just tlking out aloud wt i was thnking .. now some one tell me where is it written that color depends on co- ord sphere ?
11Why dere should b colour differ due to counter ion is what this thread is all abt!
1all due 2 the unshared pair of e-1 of both d counter ions
1hey ANI can u giv som other example than K4[Fe(CN)6) & Fe2[Fe(CN)6]
if u cant then i will share my views (& i jst think u cant)
11Wherever potassium ferrocyanate is used in qualitative analysis is an example
1k.. tell me y color differs between
[Cr(H2o)4cl2]cl.2H2O
[Cr(H2o)5cl]cl2H2O
1the reaction involves transfer of an electron when the metals differ and the co ord sphere is the same
11@Ram: Constituents of Coordination sphere have changed. But in my q, they don't! And I know only of Potassium Ferrocyanate. There may be others.
1and ani i think u r fooling others in Fe2[Fe(CN)6]
iron will exist as Fe4+ nt possible
so this compnd dont exist
1k.. can u plz tell me whether in ur q d counter ions are ionisable????
1k.. can u plz tell me whether in ur q d counter ions are ionisable????
1i too ve never seen such a complex....
but seems to exist but not...........
1i thnk yup ani bt anyways dis cmpnd doesnt exist
frm where u found it
11It's what you get when you add K4[Fe(CN)6] to any solution with Fe2+ ions.
