摘要
The title compound, [Mn4O2（O2CMe）6（MeOH）2（dbm）2]·2MeCOOH·2CH2Cl2 （Hdbm = dibenzoylmethane）, has been synthesized and structurally determined by single-crystal X-ray diffraction. The crystal belongs to triclinic, space group P/, with a = 10.729（3）, b = 12.269（3）, c = 13.085（4） A, a = 106.367（3）,β = 107.643（2）, γ = 94.771（2）°, V = 1547.9（7） A^3, Z = 1, C50H64Cl4Mn4O24, Mr= 1410.57, Dc= 1.513 g/cm^3, F（000） = 724, Rint = 0.0147, T= 293（2） K and p = 1.046 mm ^-1. The final R = 0.0359 and wR = 0.0938 for 5791 observed reflections with 1 〉 2σ（/）. The structure of the complex consists of one [Mn4（μ3-O）2]^8＋ core with four coplanar Mn atoms disposed in an extended ＂butterfly-like＂ arrangement and two O atoms triply bridging each ＂wing＂, and the peripheral ligation is provided by six by-MeCO2^-, two terminal ,μ2-dbm- groups at the two ends of the molecule, and two MeOH molecules on the central Mn atoms, lntermolecular O…H-O hydrogen bonding interactions are found within the structure of the compound.
