Abstract Multimetallic clusters have long been investigated as molecular surrogates for reactive sites on metal surfaces. In the case of the μ 4 ‐nitrido cluster [Fe 44 ‐N)(CO) 12 ] , this analogy is limited owing to the electron‐withdrawing effect of carbonyl ligands on the iron nitride core. Described here is the synthesis and reactivity of [Fe 44 ‐N)(CO) 8 (CNAr Mes2 ) 4 ] , an electron‐rich analogue of [Fe 44 ‐N)(CO) 12 ] , where the interstitial nitride displays significant nucleophilicity. This characteristic enables rational expansion with main‐group and transition‐metal centers to yield unsaturated sites. The resulting clusters display surface‐like reactivity through coordination‐sphere‐dependent atom rearrangement and metal–metal cooperativity.
