Abstract A series of four new long chain triorganotin(IV) esters containing a diazenyl-and an imino-groups appended with ferrocene scaffold were designed and synthesized. Ferrocene based metallo pro-ligands H HFcL(1) and H HFcL(2) were obtained by reacting isomeric 3-/4-ferrocenylanilines with 2-[(E)-2-(3-formyl-4-hydroxyphenyl)-1-diazenyl]benzoic acid, which upon reactions with appropriate triorganotin(IV) precursors yielded compounds namely, [nBu(3)Sn(HFcL(1))] 1, [Ph3Sn(HFcL(1)) 2, [nBu(3)Sn(HFcL(2))] 3 and [Ph3Sn(HFcL(2)) 4. Compounds 1-4 have been characterized by elemental analysis and their spectroscopic properties were investigated using IR, UV-Vis and NMR spectroscopic techniques. The molecular structures of H HFcL(1) and two representative heterobimetallic compounds 3 and 4 have been determined by X-ray crystallography. Compound 3 is a 1D polymer and 4 is a discrete molecule; their structural differences relative to those of H HFcL(1) clearly indicate the influence of the binding of the tin cluster. The redox properties of the metallo pro-ligands and their compounds were also investigated by cyclic voltammetry. (C) 2018 Elsevier B.V. All rights reserved.
