N2  - 1,2-Bis(2,2&#8242;:6&#8242;,2&#8242;&#8242;-terpyridin-4&#8242;yl)ethanone 7, an unsymmetrically linked bis-tridentatate ligand, was prepared by treatment of 4&#8242;-cyanomethylterpyridine 10 (RT, overnight) or 4&#8242;-(methoxycarbonylmethyl)terpyridine 11 (60&#176;C, 7 h) with concentrated hydrochloric acid. These conversions, which involved an unprecedented homo-coupling reaction, are discussed with the structure of 7 being confirmed by X-ray single crystal analysis. The nitrile starting material 10 was prepared by reaction of the mesylate 9, derived from the known 4&#8242;-hydroxymethylterpyridine 8 with sodium cyanide, while ester 11 was prepared by reaction of 10 with methanol in the presence of concentrated sulfuric acid.
