Triethylammonium (2,2',2'',2'''-1,2-ethanediylbis[nit-rilobis(methylene)]}tetraphenolato-N,N',O,O',O'',O''')-ferrate(III), [NH(C2H5)3][Fe(C30H28N2O4)], has been synthesized and its structure determined by X-ray diffraction. The anion, [Fe(tben)]-, shows pseudo-octahedral geometry in which the hexadentate ligand is coordinated to the high-spin ferric center by four phenolate O and two N donor atoms in facial NO2 arrangements. The O(1)-Fe-O(2) and the N(1)-Fe-N(2) bond angles of 103.6 (1) and 80.7 (1)-degrees, respectively, deviate significantly from 90-degrees as a result of the large bite angle required by the six-membered chelate rings for the equatorial configuration.
