The X-ray crystal structures of cyclopalladated complexes are reported. Reaction of {[Pd(dmba)(μ-Cl)] 2}, ( 1), (dmba=N(CH 3) 2CH 2C 6H 5) 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(1) Å, b=15.635(3) Å, c=8.352(1) Å, β=109.29°, and D calc=1.895 g cm −3 for Z=2. Complexes ( 2a) and ( 2b) crystallize together in the space group P2(1)/n with a=9.964(2) Å, b=34.228(5) Å, c=18.127(3) Å, β=91.91 °, and D calc=1.439 g cm −3.
