The synthesis and crystal structures of di-mu-dichloro-bis{[N,N-dimethylaminobenzyl-C-1,N]dipalladium(II)} and of the Cocrystals of {chloro-(triphenylphosphino)-bis[N,N-dimethylaminobenzyl-C-1,N]palladium(II) and {trans-bis(triphenylphosphino)-chloro

摘要

The X-ray crystal structures of cyclopalladated complexes are reported. Reaction of {[Pd(dmba)(mu-Cl)](2)}, (1), (dmba = N(CH3)(2)-CH2C6H5) with triphenylphosphine gave crystals containing {chloro-(triphenylphosphino)-bis[N,N-dimethylaminobenzyl-C-1,N] palladium(II)} (2a) and {trans-bis(triphenylphosphino)-chloro-[N,N-dimethylaminozyl-C]palladium(II)} (2b). Complex (1) crystallises in the space group P2(1)/c with a = 7.849(l) Angstrom, b = 15.635(3) Angstrom, c = 8.352(l) Angstrom, beta = 109.29degrees, and D-calc = 1.895 g cm(-3) for Z = 2. Complexes (2a) and (2b) crystallize together in the space group P2(1) with a = 9.964(2) Angstrom, b = 34.228(5) Angstrom, c = 18.127(3) Angstrom, beta = 91.91 degrees, and D-calc = 1.439 g cm(-3).
