The reaction of Mn 2 (CO) 10 with pap [pap = 2‐(phenylazo) pyridine, L 1 ] in boiling n‐octane affords a violet complex, [Mn(L 2 ) 2 ] ( 1 , HL 2 NH 4 C 5 N=NC 6 H 4 N(H)C 6 H 5 ). This reaction exemplifies an unusual transformation wherein the anionic tridentate ligand (L 2 ) − is formed by the fusion of phenyl imide fragment, originated from the splitting of the –N=N‐ function of L 1 , to pendant phenyl ring of the coordinated azo ligand. X‐ray structure of the manganese complex is reported.
