N2  - The bidentate ligand 1,2-bis(phosphorinan-1-yl)ethane (bpe6) reacts with iron(II) chloride to form a 2 : 1 complex trans-&#91;Fe(bpe6)2Cl2&#93; (2) which has been characterized crystallographically. Photochemically induced oxidation of trans-&#91;Fe(bpe6)2Cl2&#93; in chloroform solution affords &#91;Fe(bpe6)2Cl2&#93; + &#91;FeCl4&#93; &#8211; (9) which was also characterized crystallographically. Competitive ligand substitution reactions with Fe(PP)2Cl2 complexes &#91;PP = 1,2-bis(phosphorinan-1-yl)ethane (bpe6), 1,2-bis(dimethylphosphino)ethane (dmpe), 1,2-bis(diethylphosphino)ethane (depe) and 1,2-bis(dipropylphosphino)ethane (dprpe)&#93; show the relative qualitative chelation strengths to be dmpe &#62; bpe6 &#62; depe &#62; dprpe.
