New rhenium-tricarbonyl complexes bearing halogen-substituted bidentate ligands: structural, computational and Hirshfeld surfaces studies

Abstract

The intermolecular interactions in a series of new complexes Re(CO)₃(N,N)X (N,N is a halogen substituted bidentate N–N donor and X is Cl or Br) have been studied crystallographically and computationally. Metal-bound halogens are more effective than carbon-bound halogens in forming significant intermolecular interactions.
