The reaction of [{Cp x (CO) 2 Fe}SbCl 2 ] [ 1a : Cp x = η 5 ‐C 5 H 3 t Bu 2 ‐1,3 (Cp"); 1b : Cp x = η 5 ‐C 5 Me 5 (Cp*)] with Na 2 [Fe(CO) 4 ] or K[Co(CO) 4 ] affords the novel antimony‐transition metal cluster compounds [{μ 3 ‐SbFe(CO) 2 Cp"} 3 {Fe(CO) 3 } 4 ] (2) , [{Fe 3 (CO) 9 }{μ 3 ‐SbFe(CO) 2 Cp"} 2 ] (3) and [{μ 4 ‐SbFe(CO) 2 Cp*} 2 {Co 4 (CO) 10 (μ‐CO)}] (4) . All products were characterised by X‐ray structure analyses and other methods. Cluster 2 reveals a novel Sb 3 Fe 4 core, which does not follow the Wade−Mingos rules. Cluster 3 forms a square‐pyramidal nido ‐cluster. The Sb 2 Co 4 cluster core of 4 derives from a pentagonal bipyramid and consists of apical Sb and equatorial Co atoms with one missing pentagonal core atom.
