Cationic 2,2′-bipyridine complexes of germanium(<scp>ii</scp>) and tin(<scp>ii</scp>)

Abstract

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 ECl¹⁺ and E²⁺. Computational DFT methods were also employed to survey the bonding in the cations, along with an examination of their molecular orbitals (MOs).
