Abstract

Reaction of FeCl₂.4H₂O with 2-(-(2-(-2-hydroxy-3-methoxybenzylideneamino)phenylimino)methyl)-6-methoxyphenol (H₂L) gives the metalloligand [Fe(L)].(H₂O) (1). Reaction of metalloligand (1) with three fold of sodium dicyanamide Na[N(CN)₂] gives the new tetranuclear compound [{Fe^IINa^I(L)(EtOH)(HN(CN)₂)}(μ-O){Fe^IIINa^I(L)(NO₃)]}]_n (2) in which one of the two irons is oxidized to +3. Suitable crystals of (2) were grown by slow evaporation of ethanol solution during two weeks. The metalloligand (1) and the tetranuclear (2) complexes are characterized by IR and physical measurement. Spectroscopic evidence indicated that the Schiff base H₂L behave an N₂O₂O’₂ coordination tetradentate ligand. The structure of (2) was elucidated by X-ray diffraction analysis. The asymmetric unit of the compound contains two dideprotonated ligand molecules, two iron ions, one hexacoordinated sodium ion, one heptacoordinated sodium ion, one bidentate nitrate group, one monodentate dicyanamide unit, one coordinated ethanol molecule and an O^2- ion which acts as a bridge between the Fe^II and the Fe^III of two entities: [Fe^IINa^I(L)(EtOH)(HN(CN)₂)] and [Fe^IIINa^I(L)(NO₃)]. Bridge Fe—O(μ) bond lengths are 1.7813(14) and 1.7856(13) Å and bridging angle Fe—O—Fe is 144.78(8)°. The second terminal cyano group of the dicyanamide link another molecule complex through the heptacoordinated Na^I leading a polymeric structure. Intermolecular hydrogen bond connect the polymeric chains to develop a three dimensional structure.

Bridge Fe—O(μ) bond lengths are 1.7813(14) and 1.7856(13) Å and bridging angle Fe—O—Fe is 144.78(8)°. The second terminal cyano group of the dicyanamide link another molecule complex through the heptacoordinated NaI leading a polymeric structure. Intermolecular hydrogen bond connect the polymeric chains to develop a three dimensional structure.
