The reactions of (+)-(S)-5-s-butyl-2,2'-bipyridine (LH) and 6-(1-methylbenzyl)-2,2'-bipyridine (L'H) with Na2 and K2 give the 1 : 1 adducts (LH)MCl2 (M =Pd, 1; M = Pt, 2) and the metallated species (L')MCl (M = Pd, 3; M = Pt, 4), respectively.In complexes 3 and 4, the deprotonated bipyridine behaves as a tridentate ligand; there is coordination to the metal through the two nitrogen atoms and the ortho-carbon atom of the phenyl rong to give a six-membered metallacycle.The X-ray structure of complex 3 shows that the coordination around the palladium atom is distorted towards tetrahedral from the usual squareplanar geometry.
