Magnetically induced ring currents, aromaticity, as well as polarizability and second hyperpolarizability of the metallocenothiaporphyrins with transition metals of group VIII (Fe, Ru) and isoelectronic cations of group IX (Со+, Rh+) and metallocene-containing annulenes ((C5H5)2М[n = 18–24], where M is Fe, Co+) have been studied computationally at Density Functional level of Theory (DFT). The calculations show that the value of average polarizability of the studied compounds depends on their character of the aromaticity. Aromatic structures are characterized by larger polarizability than their corresponding antiaromatic congeners. The average polarizability of metallocenothiaporphyrins also depends on the magnitude of magnetically induced ring currents, which quantify the degree of electron delocalization.
