Title: What is the bond between Al and O for AlO6 structures?
Post by: extremesonic on May 03, 2020, 10:38:06 PM

I read some of the journal papers regarding Al hydrolysis interaction, and it is discussing about something like

[Al(OH)₅]^2-
Al(OH)₃+3H₂O

But what might be the bond between Al and O for these "highly oxidated" Al atoms?

I can understand things like Al(OH)₃, and [Al(OH)₄]^-. Al has 3 valence electrons so 3 OHs can bond with Al. For Al(OH)₄, I think 2 unpair electrons from O can close to Al to create some sort of 4th Al-O interaction.

But I'm not sure how 5th OH bond is formed with [Al(OH)₄]^-, and what might be the interaction between Al of Al(OH)₃ and O of water molecules. Are they electrostatic force?

Would you be so kind as to provide links to these publications?

I know it doesn't address you question, but:

Are they electrostatic force?

Are there non-electrostatic forces involved in bonding?
