Abstract

A magnetochemical comparison between the {Fe^III₄Ln^III₂}-type coordination clusters [Fe₄M₂(OH)₂(N₃)₂(bdea)₄(O₂CCMe₃)₅(H₂O)]NO₃·2(EtOH) (M = Dy, Y) and [Fe₄M₂(OH)₂(N₃)₂(bdea)₄(O₂CCMe₃)₄(NO₃)₂]·3(EtOH) (M = Gd, Eu; H₂bdea = N-butyldiethanolamine), of which {Fe₄Dy₂} reveals slow molecular magnetization relaxation up to 6 K, allows assessment of the exchange coupling governing the clusters’ multiplet patterns.
