Crystal structure and Hirshfeld surface analysis study of (E)-1-(4-chloro­phen­yl)-N-(4-ferrocenylphen­yl)methanimine

The substituted cyclo­penta­dienyl ring in the title mol­ecule, [Fe(C(5)H(5))(C(18)H(13)ClN)], is nearly coplanar with the phenyl-1-(4-chloro­phen­yl)methanimine substituent, with dihedral angles between the planes of the phenyl­ene ring and the Cp and 4-(chloro­phen­yl)methanimine units of 7.87 (19) and 9.23 (10)°, respectively. The unsubstituted cyclo­penta­dienyl ring is rotationally disordered, the occupancy ratio for the two orientations refined to a 0.666 (7)/0.334 (7) ratio. In the crystal, the mol­ecules pack in ‘bilayers’ parallel to the ab plane with the ferrocenyl groups on the outer faces and the substituents directed towards the regions between them. The ferrocenyl groups are linked by C—H⋯π(ring) inter­actions. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (46.1%), H⋯C/C⋯ H (35.4%) and H⋯Cl/Cl⋯H (13.8%) inter­actions. Thus C—H⋯π(ring) and van der Waals inter­actions are the dominant inter­actions in the crystal packing.
