interesting aluminum complex anions


So I just found out that aluminum can form complex anions with high-oxygen anions, including perchlorate and nitrate:
https://en.wikipedia.org/wiki/Hexanitratoaluminate
https://en.wikipedia.org/wiki/Hexaperchloratoaluminate
I also searched the forums and didnt see any previous mention of either of these compounds, so I hope others find this new and interesting. They seem like powerful oxidizer anions, so it would be especially interesting if they could form a salt with cation complexes, for instance tetramine-copper(ii) hexanitratoaluminate.

It's possible, but they're going to be extremely water-sensitive (you'll note that they're made in liquid SO2). The only water-stable aluminum-based complex ion I can think of is [Al(OH)4]-. The oxalato and hexafluoro- complexes may be water-stable, but I don;t have a cite off the top of my head.
