An octahedral tetrachlorido Fe(ii) complex with aminopyrazinium ligands from a serendipitous redox synthesis exhibiting magnetic exchange through non-covalent 3-D architectures

Abstract

An air stable, neutral Fe(II) complex with four equatorial chlorido ligands has been stabilised through a serendipitous redox process and in situ ligand protonation. A three-dimensional non-covalent network composed of halogen bonding and π–π stacking promotes magnetic exchange interactions though the lattice. The electronic structure has been investigated using DFT.
