A tetranuclear iron(II)–sodium complex formed from the complexation of sodium ethoxide by N,N′-ethylenebis(3-hydroxy-1-methylbut-2-enylideneaminato)iron(II)

摘要: The reaction of N,N′-ethylenebis (3-hydroxy-1-methylbut-2-enylideneamine)(H2acacen) with FeCl2 in the presence MeONa afforded iron(II) dimeric complex [Fe(acacen)]2, which reacted EtONa to form a tetranuclear [Fe(acacen)(NaOEt)]2, where two atoms are five-co-ordinate and doubly bridged by [EtONa]ion pair.
