• The cyanate-bridged cyclopalladated compound [Pd(C 2 ,N-dmba)(μ-NCO)] 2 (dmba=N,N-dimethylbenzylamine) reacts in acetone with pyrazole (pz), 3,5-dimethylpyrazole (dmpz), imidazole (imz) and 2-methylimidazole (mimz) to give [Pd 2 (C 2 ,N-dmba) 2 (μ-NCO)(μ-pz)] ( 1 ), [Pd 2 (C 2 ,N-dmba) 2 (μ-NCO)(μ-dmpz)] ( 2 ), [Pd(C 2 ,N-dmba)(NCO)(imz)] ( 3 ) and [Pd(C 2 ,N-dmba)(NCO)(mimz)] ( 4 ), respectively. The compounds were characterized by elemental analysis, IR spectroscopy and TG. The thermal decomposition of the compounds occurs in three consecutive steps and the final decomposition products were identified as Pd(0) by X-ray powder diffraction. The thermal stability order of the complexes is 2 > 3 > 1 > 4 .
