Abstract

The first of the title compounds, [Fe(C12H15N6P)2][FeCl4].4CH4O, is the first homoleptic bis(ligand)iron(II) species reported for this phosphorus bridgehead ligand; interestingly, the complex is isomorphous with its tris(1-methyl-1H-imidazol-2-yl)methanol counterpart, the second of the title compounds, [Fe(C13H16N6O)2][FeCl4]2Cl. In both compounds, the Fe atom of the cation lies on an inversion centre. The structure determinations presented here allow an interesting comparison of iron(II) and iron(III) species in similar coordination environments.
