Abstract
The complex [{Fe(tmpa)(H2O)}2O](ClO4) 4·3H2O·0.25C2H5OH contains a near-linear, dinuclear cation (FeOFe ∠=176.1(5)°) with average Fe-μ-O2- (1.783(7) Å), Fe-apical N (2.244(11) Å), Fe-pyridyl N (2.125(10) Å) and Fe-O(aqua) (2.082(8) Å) bond lengths that are essentially identical for the two iron centers. Both tmpa apical nitrogen atoms are trans to the oxo bridge, in contrast to the unsymmetric structure of [(OH)(tmpa)FeOFe(tmpa)(H2O)]3+, for which one apical N atom is trans to the μ-O2- group while the other is trans to the hydroxo ligand.
