摘要：

A new hetero-tetranuclear complex [(Mn2Ni2II)-Ni-III(HL)(2)L-2(OAc)(2)(CH3OH)(2)]CH3OH (1) has been synthesized and fully characterized, where H2L is N-(2-hydroxy-5-fluro-methylphenyl)-3-imine-2-propanol. The X-ray diffraction analysis of 1 shows that four metal ions as well as coordinated 0 atoms in one molecular unit exhibit a dicubane-like core with two missing vertexes. The extension of the magnetic exchange in 1 has been evaluated by means of a spin Hamiltonian, yielding the parameters of J(1) = -11.85 cm(-1), J(2) = -6.44 cm(-1) and J(3) = 0.34 cm(-1), D = 2.26 cm(-1) and g = 2.12, assumed under same anisotropy D and g. And the DNA cleavage ability of 1 was also investigated. (C) 2012 Elsevier B.V. All rights reserved.
