Abstract
The wheel-shaped heptanuclear cluster complex {[Mn(4)Na(3)(thmp)(2)(acac)(6)(H(2)O)(6)]CH(3)COO} x 4 H(2)O is the first heterometallic mixed-valent disklike compound with apical alkali-metal ions. The weak ferromagnetic interaction between the central Mn(4+) ion and the peripheral Mn(2+) ones leads to a high-spin ground state (S = 9).
