Abstract / Description of output

We report on the magnetic properties of the enneanuclear mixed-valent single-molecule magnet [Mn9O7(OAc)(11)(thme)(py)(3)(H2O)(2)] (1). Using inelastic neutron scattering (INS) spectroscopy, we have confirmed the S= 17/2 cluster ground state of 1. Furthermore, we have determined accurately the anisotropy parameters of the zero field split ground state. The cluster I exhibits 2 a strong negative axial anisotropy D[S-z(2) - S(S + 1)/3] where D = -0.249(5) cm(-1). It is necessary to include an axial higher order term (B-4(0)) in the effective spin Hamiltonian to account for the experimental data. 4 (c) 2005 Elsevier Ltd. All rights reserved.
