Abstract

A new mononuclear tetracyanometallic complex, (n-Bu₄N)[(dbphen)Fe(CN)₄] (1, dbphen = 5,6-dibromo-1,10-phenanthroline), has been prepared by reacting [(dbphen)Fe^II(py)₂(SCN)₂] and KCN in water and further oxidized with chlorine. With the use of 1 as building block, two trinuclear Fe₂M complexes, [(dbphen)₂Fe₂(CN)₈Cu(Me₃tacn )]·3H₂O (2), [(dbphen)₂Fe₂(CN)₈Ni(dabhctd)]·2 H₂O (3) and a chain complex of squares [(dbphen)₂Fe₂(CN)₈Co(MeOH)₂] _n (4), have been synthesized and structurally characterized. Magnetic studies show ferromagnetic coupling between Fe^III and M^II (M = Cu, 2; Ni, 3) ions bridged by cyanides in complexes 2 and 3, while complex 4 exhibits meta-magnetic behavior.
