Cationic 2,2'-bipyridine Complexes of Germanium(ii) and Tin(ii)

We present the first systematic study of 2,2'-bipyridine complexes of E(ii) cationic acceptors (E = Ge, Sn). The complexes were comprehensively characterized by spectroscopic and crystallographic methods to yield complexes of ECl and E. Computational DFT methods were also employed to survey the bonding in the cations, along with an examination of their molecular orbitals (MOs).
