By high‐resolution electron microscopy, chemical intergrowth was studied of dimeric Mo 10 O 16 and trimeric Mo 14 O 22 clusters in reduced tin oxomolybdates within the Sn x Mo 10 O 16 Sn y Mo 14 O 22 system. The variety of observed intergrowth patterns includes polysynthetically twinned structures as well as a number of different superstructures. For an orthorhombic superstructure formed by alternating layers of dimeric and trimeric clusters, the lattice parameters and the Sn content were determined. The chemical reason for the amazing abundance of structures in the considered system is discussed.
