New mononuclear tin(IV) complexes were obtained via condensation of tin oxides (Ph2SnO and Et2SnO) with acenaphthene-based bis(thiosemicarbazones). The structure of the complexes was confirmed using 1H, 13C and 119Sn NMR spectroscopy, as well as by X-ray diffraction analysis. The electronic and redox properties of complexes 1–5 were studied using UV spectroscopy and cyclic voltammetry (CV). It was shown that the electrochemical reduction of complexes 1–5 is quasi-reversible. Radical anion derivatives of complexes were described using CV and ESR spectroscopy. The second wave of electrochemical reduction of 1–4 is accompanied by further chemical transformations, while the electroreduction of complex 5 leads to the formation of persistent dianion species.
