Abstract

A C,N-bound palladacycle dimer has been synthesised by reaction of 2-(thiophen-2-yl)pyridine, LH, with palladium acetate in acetic acid. Characterisation by single crystal X-ray diffraction showed the palladacycle dimer, [(L)Pd(OAc)](2), to crystallise in the monoclinic space group P2(1)/n with cell parameters a = 9.5853(1) , b = 19.1332(3) , c = 12.3889(2) , beta = 103.732(1)A degrees. Reaction of [(L)Pd(OAc)](2) with triphenylphosphine afforded a trans-substituted monomeric complex, [(L)PdPPh(3)(OAc)] which was also analysed using single crystal X-ray diffraction. [(L)PdPPh(3)(OAc)] crystallises in the monoclinic space group P2(1)/c with cell parameters a = 9.4839(1) , b = 11.0427(2) , c = 26.0770(4) , beta = 95.022(1)A degrees.
