摘要：
A hexanuclear cluster [(Cp*Dy)(6)K4Cl16(THF)(6)], [Cp*Dy](6), has been constructed from six {Cp*Dy-III} synthons in which the strongly coordinating Cp*(-) caps determine the local anisotropy axes. Structural characterization of [Cp*Dy](6) shows two almost parallel triangular (Cp*Dy)(3) fragments that are linked by the K+ and Cl- ions. Magnetic measurements reveal slow thermal relaxation and fast quantum tunneling relaxation in the absence of an external dc field. After applying a weak dc field, the quantum tunneling relaxation is efficiently suppressed, giving a sizable energy barrier of 561 K, which represents the current record energy barrier for high nuclearity organometallic SMMs.
