Ternary aromatic and anti-aromatic clusters derived from the hypho species [Sn2Sb5]3−

Abstract

Ternary heterometallic clusters often display intriguing structures and bonding. Here the authors prepare four [Sn2Sb5]3−-based clusters stabilized by coordination of a transition metal ion; analysis of their electronic structure reveals that the resulting cluster displays globally aromatic or antiaromatic character depending on the transition metal ion.
