摘要

The reaction of 1-(2-pyridyl)-3-(p-tolyl)propane-1,3-dione (HL) with [Mn3O(O2CPh)6(H2O)(py)2] in CH2Cl2 affords a mixed-valence Mn3II Mn3III hexanuclear complex [Mn6O2(O2CPh)8L3] (1). Complex 1 contains a [Mn3II Mn3III4 - O)2]11 + core, which is a new structural type in the family of Mn6 complexes. Variable temperature magnetic susceptibility and magnetization measurement of complex 1 have been carried out. The magnetic data indicate that complex 1 has a ground state spin value of S = 7/2 with significant magnetoanisotropy as gauged by the D value of -0.46 cm-1. The frequency dependence of the out-of-phase component in alternating current magnetic susceptibilities for complex 1 indicates the slow magnetic relaxation of a superparamagnetic molecule.
