Abstract: Reaction of H3L with Cd(NO3)2·4H2O in DMF at 150 °C for 3 days affords the metal–organic nanosphere [Cd66(?3-OH)28(?3-O)16(?5-NO3-O,O,O?,O?,O?,O?)12(L)20(?2-DMF)12?(DMF)9]. The cluster is composed of a spherical shell of 66 Cd(II) cations bridged by 28 ?3-hydroxide, 16 ?3-oxo, and five ?5-NO3– anions surrounded by a shell of 20 tripodal capping ligands (L) and 12 DMF ligands. The 66 Cd(II) cations and 12 NO3– anions form a polydeltahedron that has 78 vertices [Cd(II) or NO3–] (V), 228 edges (E), and 152 triangular faces (F), giving it an Euler characteristic (?) of 2 (? = V + F – E). Reaction of H3L with Cd(NO3)2·4H2O at lower temperatures or with CdCl2 affords coordination polymer frameworks instead of nanospheres.
