Minghetti, Giovanni and Cinellu, Maria Agostina and Chelucci, Giorgio Adolfo and Gladiali, Serafino Gabriele and Demartin, Francesco and Manassero, Mario (1986) Palladium(II) and platinum(II) derivatives with chiral 2,2′-bipyridines: X-ray structure of C18H15ClN2Pd; C- and N-intramolecular coordination in a six-membered metallacycle. Journal of Organometallic Chemistry, Vol. 307 (1), p. 107-114. ISSN 0022-328X. Article. Full text not available from this repository. DOI: 10.1016/0022-328X(86)80181-4 AbstractThe reactions of (+)-(S)-5-s,butyl-2,2′-bipyridine (LH) and 6-(1-methylbenzyl)-2,2′-bipyridine (L′H) with Na2[PdCl4] and K2[PtCl4] 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 ring 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 square-planar geometry.
