Two layerlike supramolecular assemblies that consist of Ag‐supported B‐Anderson‐type clusters (H 2 bpp)[Ag{AlMo 6 (OH) 6 O 18 }] · 2.5H 2 O ( 1 ) and (H 2 bpe)[Ag(OH 2 ){AlMo 6 (OH) 6 O 18 }] ( 2 ) [bpp = 1,3‐di(4‐pyridyl)propane; bpe = 1,2‐di(4‐pyridyl)ethylene] have been synthesized and characterized. X‐ray diffraction analysis reveals that the supramolecular structures of two compounds are built upon alternative arrangements of inorganic anionic and organic cationic layers. In 1 and 2 the oxophile silver centers have different coordination modes to bridge Anderson‐type clusters into 2D inorganic anionic layers. There are extensive noncovalent forces among inorganic anions and organic cations to construct 3D supramolecular frameworks of compounds 1 – 2 . The preliminary experiments show that the two crystals possess an adsorption–desorption property for methylene blue (MB). Crystal 2 shows a very fast adsorption rate towards MB, and a relatively high value (ca. 90 %) can be reached within 15 min.
