Abstract

The novel mu-oxo-diiron complex [Fe2O(BPHPA)2](ClO4)4 [BPHPA is (6-hydroxymethyl-2-pyridylmethyl)bis(2-pyridylmethyl)amine, C19H20N4O], contains a binuclear centrosymmetric [Fe2O(BPHPA)2]4+ cation (the bridging O atom lies on an inversion centre) and four perchlorate anions. Each iron ion is coordinated by four N atoms [Fe-N = 2.117 (5)-2.196 (5) A] and one O atom [Fe-O = 2.052 (5) A] from a BPHPA ligand, and by one bridging oxo atom [Fe-O = 1.7896 (9) A], forming a distorted octahedron. There are hydrogen bonds between the hydroxy group and perchlorate O atoms [O-H...O = 2.654 (7) A].
