| Abstract: | With aqueous acidic iron(III) chloride, the three diamines ethylenediamine (en), tetramethylethylenediamine (tmeda) and 4:4′‐tetramethyldiaminodiphenylmethane (ddmp) yield the aquapentachloroferrate(III) and a pair of [FeCl4]? Cl? double salts, respectively. Their structures indicate that N–H···Cl hydrogen bonding is present, but the Fe···Fe distances are all quite long. The magnetic data show that, while all the materials display antiferromagnetic coupling on cooling, in none of the cases was any transition observed above 1.8 K. |
