【 摘 要 】

Mn12O12(O2CCH2CH2CH2Cl)16(H2O)4] (noted as Mn12-BuCl), a new polynuclear complex of manganese chlorobutyrate has been successfully prepared by substitution of acetate with 4-chlorobutyric acid. The Mn12-BuCl crystallizes into triclinic space group P-1 with a = 14.5560(11) A, b = 14.5819(11) A, c = 27.265(2) A, �? = 84.1140(10)�?, �? = 88.805(2)�?, �? = 89.8820(10)�?, and Z = 2. The local environments of manganese 3+ and 4+ ions of the title compound are close to those of other Mn12 compounds. The electrochemical data for Mn12-BuCl involve reversible reactions of two-electron reductions. The Mn12-BuCl also presents magnetic relaxation below 10 K implying that each molecule behaves as a single molecule magnet.
