摘要：
Unprecedented 18-molybdosulfite Dawson clusters encapsulate two pyramidal sulfite ions as templates, and exhibit a short S⋯S interaction between the two ions, which was characterized by DFT calculations. The [Mo 18O54(SO3)2]4- ion is the first discrete thermochromic polyoxometalate cluster: its color varies from pale yellow at 77 K to deep red at 500 K (see picture).
