N,N′-Bis(3-chloro-2-fluorobenzylidene)ethane-1,2-diamine

Abstract

The mol­ecule of the title centrosymmetric Schiff base compound, C16H12Cl2F2N2, adopts an E configuration with respect to the azomethine C=N bond. The imino groups are coplanar with the aromatic rings. Within the mol­ecule, the planar units are parallel, but extend in opposite directions from the dimethyl­ene bridge. An inter­esting feature of the crystal structure is the short inter­molecular Cl⋯F [3.1747 (5) Å] inter­actions, which are shorter than the sum of the van der Waals radii of these atoms. These inter­actions link neighbouring mol­ecules along the b axis. The crystal structure is further stabilized by π–π inter­actions, with a centroid–centroid distance of 3.5244 (4) Å.

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

“…The syntheses and crystal structures of the halogensubstituted bidentate N,N-ligands (Scheme 1) and the 32ClFenReBr complex (abbreviated as C1), have been reported previously. [37][38][39][40][41][42] The preparation of all of the ReIJI)tricarbonyl complexes has been achieved using literature methods. 43…”
