Five single‐side organic decorated Anderson‐type molybdoaluminates have been synthesized from the reaction of the Na 3 (H 2 O) 6 [Al(OH) 6 Mo 6 O 18 ] · 2H 2 O cluster and RC(CH 2 OH) 3 ligands [R = CH 2 OH, NH 2 , CH 2 CH 3 , NHCH 2 COOH, CH 2 OCH 2 C(CH 2 OH) 3 ], followed by the addition of TBA · Br {TBA = [N(C 4 H 9 ) 4 ] + }. The prepared compounds possess an identical Anderson‐type structural frame in each case, wherein three of the six hydroxy groups surrounding the Al III heteroatom are substituted by one RC(CH 2 OH) 3 group, forming asymmetric single‐sided organically decorated clusters. The compounds demonstrate the simplest synthesis of covalent organic decoration for the single‐sides of molybdoaluminates. All the prepared compounds in the present study were synthesized in aqueous solution and characterized by elemental and TG analysis, IR and 1 H NMR spectroscopy, and single‐crystal X‐ray diffraction analysis. In addition, the supramolecular structures of these compounds based on the hydrogen bonding have also been discussed. The method reported here provides a common approach for the asymmetric functionalization of Anderson‐type molybdoaluminates.
