The N ‐acylation of the cyano ligand in the binuclear complex anion of Na[Fe 2 (CN)Cp 2 (CO) 3 ] with dicarboxylic acid chlorides causes the cleavage of the CN triple bond and the attachment of a second complex anion to form the surprisingly stable, permetalated, axially chiral 2‐azaallenium ion 1 , which can be isolated as a chloride. This conversion of CN − has parallels in CO chemistry both in multinuclear clusters and on surfaces. [Fe] = FeCpCO.
