Synthesis and Crystal Structures of Carbonyliron and Cyclopentadienyliron Dinuclear Complexes of 2,3‐Diethyl‐1,4‐dihydro‐1,4‐dimethyl‐1,4‐diboranaphthalene * Reactions of the 1,4‐Diboranaphthalene derivative 1a with (CO) 3 Fe(C 8 H 14 ) 2 lead to the orange anti dinuclear complex [(CO) 3 Fe(η 6 , η 4 ‐ 1a )Fe(CO) 3 ] ( 4a ) and to the cherry‐red syn complex [(CO) 3 Fe(η 4 , η 6 1a )Fe(CO) 2 ] ( 5a ). The X‐ray structure of 5a reveals an Fe—Fe interaction (2.98 Å), 1a reacts with [(C 5 H 5 )Fe(C 8 H 12 )] 2 Zn to give the 30‐VE triple‐decker 7a , in which the diene of the benzo ring can be complexed with a Fe(CO) 3 moiety to yield the trinuclear complex 9a .
