for a homework problem it says to build both the high spin and low spin complex ion

and it gives me
spin of Fe (ox)3 3-
low
high

I don't understand what high spin and low spin is and I don't know what
Fe (ox)3 3- is suppose to be

i have no idea either. i can't find it in my book =(

• chemistry -

Fe(ox)3 3- is Fe(C2O4)3 3- from the lab. The energy for high is 2/5 of the energy for the low. Make sure you build your molecule correctly and select a charge of -3. Your answers should come out to be -3439.31 for the low spin and -1375.724 for the high spin.

How are you getting the high spin energy? I keep trying with 5 unpaired electrons, but I get something completely different.. :\

And do you guys have answers for prob 9? I spend 4 hours doing the computation on Spartan and it came up wrong...

lol im having trouble with that too :(

same here =[

Why is the energy for high 2/5 of the energy for the low.

• chemistry -

?*

I think that is the ratio of energy difference between high and low spin, read it on wikipedia or something.
