A series of η 1 ‐borazine complexes were obtained by the reaction of trichloroborazine with Na[(η 5 ‐C 5 R 5 )Fe(CO) 2 ]. The compounds [{(C 5 R 5 )(CO) 2 Fe} n Cl 3− n B 3 N 3 H 3 ] ( 1a , n = 1, R = Me; 1b , n = 2, C 5 R 5 = C 5 H 4 Me; 1c , n = 3, R = H) have one to three iron−boron σ bonds and Fe−B π‐interactions can be ruled out from the spectroscopic and structural results. All new borazine complexes were isolated as orange crystalline solids and characterized by multinuclear NMR methods and IR spectroscopy. The structure of 1b in the crystalline state was also determined by a single‐crystal X‐ray study.
