Labile and Stability, and Nomenclature
« on: November 25, 2005, 03:04:23 PM »
Wondering the underlying difference between labile and stability. I know that a labile complex is a complex which quickly reaches equilibrium with the ligands in a surrounding solution; readily undergoing change or breakdown.

Now to me stability seams to be the opposite of labile because a non-labile complex the ligands are firmly attached and don’t come off, therefore making the complex more stable.  And stability is the complexes ability to not fall apart.

Also wondering whats wrong with my naming

[Co(NH3)5(NO2)]Cl2

Pentaamino-nitrocobalt(+2) chloride

But this isn’t the answer my instructor is looking for so I’m just wondering if someone would be able to help me out.

Thanks,
Luke

What about Nitro-pentammoniacobalt(2+) dichloride?

the official name for coordinated NH3 is 'amine' not amino or ammonia

comprehensive inorganic chemistry by cotton and wilkinson has a good section on nomenclature.  Available at all university libraries.

I don't think stability is considered a kinetic effect.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

hey thanks
it's actually ammine for a complex but i had it mixed up with -ide and -ite to-o, and -ate to -ato. just figured it was ammino  :P. i'm assumeing that was my 'small' error i had.
