摘要：

In this paper, we present a mixed valence f-d Ce6Mn (4) (III) compound having formula [Ce (6) (IV) Mn (4) (III) (mu(4)-O)(4) (mu(3)-O)(4)((O2CBu)-Bu-t)(12)(ea)(4)(OAc)(4)]center dot H2O (1), which is obtained by the reaction of hydrated lanthanide nitrate, pivalic acid, and ethanolamine in MeCN as a solvent. The single crystal X-ray diffraction analysis demonstrates that the central core consists of an octahedron with four triangular pyramids added to four related faces or as an octahedron encapsulated in a tetragon. The fitting of magnetization data using the anisotropic model gives D = 2.13 cm(-1) and g = 1.97 (D is the axial zero-field splitting parameter).
