Abstract
The syntheses and structures of a pair of neutral one-dimensional (1D) Fe-anilate based coordination polymers, Fe(Fan)(4,4′-bipy)2 (Fann− = deprotonated 3,6-difluoro-2,5-dihydroxy-1,4-benzoquinone; 4,4′-bipy = 4,4′-bipyridine) and Fe(Clan)(OPPh3)2 (Clann− = deprotonated 3,6-dichloro-2,5-dihydroxy-1,4-benzoquinone; OPPh3 = triphenylphosphine oxide), are reported. In the case of Fe(Fan)(4,4′-bipy)2, the Fe centre is in the +2 oxidation state and the Fan ligand is present in its quinoidal, dianionic form. In contrast, the structurally similar Fe(Clan)(OPPh3)2 chain contains Fe centres and chloranilate ligands in oxidation states close to +3 and −3 respectively at low temperature. It is suggeste..
