Title: Structure of [Al3(OH)11]2-
Post by: SinkingTako on May 08, 2014, 04:05:06 AM

Anyone knows the structure of [itex][Al_3(OH)_{11}]^{2-}[/itex]? Can't seem to find the structure anywhere. It is not a Keggin.

I think that there must be a five coordinated aluminum.

Is there 5 coordinated aluminum? Does anyone know / can find any paper about it? I propose something like 2 tetrahedra and 1 octahedral where the corners are joined to each other, but looks unlikely.

The only thing there is online is this German PhD thesis, which cites Cotton's Advanced Inorganic Chemistry, but Cotton has no citations....

Any help greatly appreciated!
