From one- to two- and three-dimensional MAS NMR solid state experiments involving 31P and 27Al we show that the structure of microporous alumino-phosphate AlPO4 40 contains at least four times more sites than expected and we attribute two types of AlIV sites. The newly described 27Al-31P MQ-HMQC opens new possibilities in describing details of three dimensional bounded networks.
