A Chiral Tetrahedral Framework with Tetrahedral Guests for Catalysis and Photoluminescence

Presented
here is a chiral three-dimensional indium­(III)-organic
compound [In­(5-Aip)2]·(TPP)·4H2O (1; 5-Aip = 5-aminoisophthalate, TPP = tetraphenylphosphonium).
The structure of 1 features an unusual tetrahedral anionic
framework containing tetrahedral TPP guests. This compound shows interesting
photoluminescent properties and notable catalytic activity on the
diethylzinc addition to benzaldehyde. The results reveal that the
employment of tetrahedral TPP cations as guests can not only direct
the formation of a tetrahedral framework but also help on the improvement
of physical properties.
