The organometallic tridentate ketoamine or enaminone compound, (η 5 -Cp)Fe(η 5 -C 5 H 4 )-C(=O)-CH=C(Me)-NH-C 6 H 4 -o-NH 2 , undergoes an intramolecular cyclocondensation promoted by Cu(ClO 4 ) 2 ⋅6H 2 O (2:1 molar ratio) affording the neutral 2-ferrocenyl-4-methyl-1,5-benzodiazepine, 1. However, when the molar ratio used is 1:1, the ketoamine or enaminone compound transforms into the 2-ferrocenyl-4-methyl-1,5-benzodiazepinium cation, [2] + . The X-ray molecular structure of 1 exhibits a seven-membered ring with a boat conformation, and two folding dihedral angles along the N(1)-N(2) and C(11)-C(13) axes. In the case of [2] + , the structure shows only one folding dihedral angle along the N(1)-N(2) axis. A rationalization of the properties of 1 and [2] + is provided through DFT calculations.Keywords: Organometallic diazepine, organometallic diazepinium, DFT calculations, X-ray structures, ferrocenyl ketoamine, ferrocenyl enaminone. INTRODUCTION It is well known in the literature that reactions of β-diketones with 1,2-diamines generally yield symmetrical 2:1 tetradentate Schiff bases whatever their proportion.
