文摘
- •
A new silicogermanate was hydrothermally synthesized using triethylisopropylammonium cation as SDA in fluoride medium.
- •
PKU-20 contains 10-ring channels intercrossed by 12-ring pockets.
- •
The framework of PKU-20 is built by the alternate stacking of sti and asv layers.
- •
The scheme for slicing off the asv layer from the ASV framework is illustrated.
- •
A composite building unit, D4R-lau-D4R, represents the characteristic of the asv layer.
