Abstract: Two iron complexes of the tridentate ligand 2,4,6-tri-2-pyridyl-1,3,5-triazine (tpt, C₁₈H₁₂N₆) have been isolated and characterized. One is [Fe^II(tpt)₂]Cl₂·4H₂O, (II), and the other is the title dinuclear complex, [Fe^III₂Cl₄(-O)(tpt)]·2H₂O, (III), which has been crystallographically characterized. The coordination sphere around each Fe atom is a distorted octahedron formed by three N atoms from the tridentate site of one tpt ligand, coordinated in a meridional fashion, two Cl^- ions cis to the central donor of the tpt ligand, and an oxo bridging ligand trans to the tpt ligand. The Fe-N distances are in the range 2.124 (2)-2.202 (3) Å, the Fe-O-Fe angle is 176.13 (14)° and the FeFe separation is 3.536 (2) Å.
