Abstract :
The heterometallic MnII4NiII2 title compound has been synthesized and characterized by X-ray crystallography. The compound consists of a Ni-Mn-Ni linear moiety, [{Ni-((mu)-NO)3}2-Mn], linked by oximate bridges and three Mn(II) hfac terminal units attached by oximate oxygens in a di-(mu)-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.
