What is the coordination number of K4(FeCN6)? I know the answer but I don't know how we will get it. Please explain me in detail?

Question

Arun · Answer

EAN means metal atomic no. Minus oxidation no.of metal atoms plus 2× coordination number,which is equal to next atomic number. In k4(fe(cn)6) , central atom Fe. I..e, 26. Oxidation no.=4(x(-1)6) =2 So Fe is +2 Coordination no=2×6 =12 Then EAN =26–2×12 =36 36 is stable configuration.

Vikas TU · Answer

Dear student

can be calculated as follows,

4(+1) + x + 6(-1) = 0

Hence x = +2.

K3[Fe(CN)6] , we know that Potassium, K, has an oxidation number of +1

The oxidation number of CN= -1, so 6*CN has an oxidation number of -6 so therefore

Fe - 6 = -3

Fe = -3 + 6 = +3

The oxidation number of Fe is +3
