Differences in the chemical properties of phosphorus and antimony enable synthesis heteroditopic derivatives whose can be modified by altering pnictogen substituents. In this work, 1-(diphenylstibino)-2-(dicyclohexylphosphino)ferrocene, [Fe(η5-1-Ph2Sb-2-Cy2PC5H3)(η5-C5H5)] (1), corresponding phosphine chalcogenides [Fe(η5-1-Ph2Sb-2-Cy2P(E)C5H3)(η5-C5H5)] (E = O, S, Se) catecholatostiboranes [Fe(η5-1-Ph2(Cl4C6O2)Sb-2-Cy2P(E)C5H3)(η5-C5H5)] void, were examined, with a focus on intramolecular donor-acceptor interactions between Experimental data theoretical analysis consistently indicated that these described as bonding Lewis acidic lone pair at substituent (either or chalcogen atom) they are significantly stronger stiboranes due to increased acidity Sb atom. Noncovalent also observed chlorogold(I) complexes obtained from 1 catecholatostiborane [Fe(η5-1-Ph2(Cl4C6O2)Sb-2-Cy2PC5H3)(η5-C5H5)] P-donors. As shown experiments Au-mediated cyclization N-propargylbenzamide, noncoordinated group influenced catalytic Au(I) complexes. Notably, an Cl → bond affected molecular geometry Pd(II) complex [PdCl2(1-κ2P,Sb)], which turn suggested structural influence exerted ligands type needs assessed care.
