Abstract

The heterometallic Mn^II₄Ni^II₂ title compound has been synthesized and characterized by X-ray crystallography. The compound consists of a Ni-Mn-Ni linear moiety, [{Ni-(μ-NO)₃}₂-Mn], linked by oximate bridges and three Mn(II) hfac terminal units attached by oximate oxygens in a di-μ-oxo fashion, forming a novel heterometallic cluster: Mn{Mn(hfac)₂}₃{Ni(pao)₃}₂ (1). Magnetic measurements reveal the antiferromagnetic nature of the oximate pathway between Mn(II) and Ni(II) metal ions, which imposes an unusual high-spin ground state (S = 8) for 1.
