Abstract
A fully conjugated acyclic diimine ligand, H4L3, formed from 1,4-diformyl-2,3-dihydroxybenzene and 2-aminophenol, was reacted with iron(II) acetate to give the hexanuclear complex [Fe-6(III)(L-3)(4)(mu-OMe)(mu-OH)(MeOH)(4)] (2). Crystals of 2 center dot ADPOX center dot 7.5MeOH center dot H2O, where ADPOX is 2-amino-10,10a-dihydro-3H-phenoxazin-3-one, were obtained by slow evaporation and the X-ray structure determination revealed that the six octahedral iron(III) ions are bridged by four fully-deprotonated (L-3)(4-) ligands that are arranged in a [2 x 2] grid-like arrangement relative to one another.
