A dodecaholmium wheel of [Ho₁₂(L)₆(mal) ₄(AcO)₄(H₂O)₁₄] (1; mal = malonate) was synthesized by using p-/tert-butylsulfonylcalix[4]arene (H₄L) as a cluster-forming ligand. The wheel consists of three fragments of mononuclear A^3- ([Ho(L)(mal)-(H₂O)]^3-), trinuclear B ^3- ([Ho(H₂O)₂ (mal)(Ho(L)(AcO)) ₂]^3-), and C³⁺ ([Ho(H₂O) ₂]³⁺), and an alternate arrangement of these fragments (A^3--C³⁺_B^3-_C³⁺_A ^3-_C³⁺_B^3-_c³⁺_)resuits in a wheel structure. The longest and shortest diameters of the core were estimated to be 17.7562(16) and 13.6810(13) Å, respectively, and the saddle-shaped molecule possesses a pocketlike cavity inside.
