Abstract
The organometallic zwitterion (η5-C5H3MeBCl3)Fe(CO)3 (2) is isolated as a minor product from the reaction between the sodium salt of the anion [η5-C5H4Me)Fe(CO)2]‾ and boron trichloride. The crystal structure of 2 [P21/n, a = 7.3927(5) Å, b = 13.8027(9) Å, c = 12.2759(9) Å, a = γ = 90°, β = 92.517(3)°] features discrete molecules in which the coordination sphere of the iron center comprises three carbonyls and a novel η5-C5H3MeBCl3) ligand, derived from attack of BCl3 on the (η5-C5H4Me) moiety of the parent compound. The isolation of 2 confirms that the nucleophilic properties of organometallic anions of the type [η5-C5R5)M(CO)n]‾ (M = Fe, Ru, n = 2; M = Mo, W, n = 3) are not confined to the metal center, or to the carbonyl oxygens (examples of which have previously been reported) but also encompass the cyclopentadienyl ligand.
