A chair‐within‐a‐chair arrangement of the twelve copper atoms (bottom left) is characteristic of one of the complexes reported here; the other complex features two Cu tetrahedra sharing a common vertex (bottom right). Both were isolated from the reaction mixture [Cu 2 (O 2 CMe) 4 (H 2 O) 2 ]/(py) 2 CO in MeCN. Magnetic susceptibility data show that the heptanuclear complex has an S = 1/2 ground state.
