Naming complex ions
« on: April 28, 2008, 04:31:01 PM »
I have to name 3:

Na3[Co(CN)6] ... i think it would be sodium hexacyanocobaltate(III)

but I am lost with the next two:

[Fe(NH2CH2CH2NH2)2(NO2)2]Cl

[Pt(NH3)4I2][PtI4]

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

H2NCH2CH2NH2 is ethylenediamine and there is two of them, so you should name it bisethylenediamine for the first complex compound.  After that the name should be straight foward.

i'm not sure if this is relevant or not, but for future reference, H2NCH2CH2NH2 is often abbreviated as "en." it is a bidentate, which means it bonds through two atoms, and therefore counts double towards the coordination number, which is good to know when calculating the metal's charge
