Abstract

2-(2′-Pyridyl)-3,4,5,6-tetraphenylpyridine 2 (HL), a ligand with both N,N-bidentate and N,N,C-terdentate coordination potential, was prepared in excellent yield by the Diels–Alder [2+4] cycloaddition of 2-cyanopyridine and tetraphenylcyclopentadien-1-one. Monometallic Pd(II) and Rh(III) complexes were formed which exhibit both types of ligand coordination (trans-[RhCl2(L)(NCMe)] 3, cis-[RhCl(L)(NCMe)2]PF64, cis-[RhCl2(HL)2]PF66, [RhCl(L)(HL)]PF67, [Rh(L)2]PF68, [Pd(OAc)(L)] 9 and [Pd(η3-methallyl)(HL)]PF610). The molecular structures of the ligand and six complexes, including the chloro-bridged dimer [RhCl(L)(µ-Cl)]25, were obtained by single crystal X-ray diffraction.
