The X-ray crystal structures of [NHR3](2)[Fe4S4X4] (X = PhS, R = Et or (n) Bu; X = Cl, R = (n) Bu), reported in this paper, show NHaEuro broken vertical bar X interactions between the cation and the cubanoid cluster. Comparison of the cluster dimensions in [NHR3](2)[Fe4S4X4] with those reported earlier for [NR'(4)](2)[Fe4S4X4] (R' = Me, X = PhS; R' = Et, X = Cl) indicates that N-HaEuro broken vertical bar X interactions have a negligible effect on the dimensions of the cluster. The relevance of these structures to understanding where on [Fe4S4X4](2-) protonation labilises the cluster to substitution is discussed.
