Popis: The reaction of cis-dichlorobis(2,6-xylylisocyanide)palladium(ii) with 2-aminopyrazine affords a binuclear palladium complex, in which one of the metal atoms is involved in the palladacyclic ligand. In the contrast, the coupling of isocyanide ligands in cis-dichlorobis-(2,6-xylylisocyanide)palladium(ii) with another C-amino aza-substituted heterocycle, viz.,4-acetyl-3-amino-5-methylpyrazole, gives a mononuclear cationic palladium diaminocarbene complex. Both compounds were characterized by elemental analysis, IR spectroscopy, 1H, 13C{1H}, DEPT90/DEPT135, and 1H,13C-HSQC/1H,13C-HMBC NMR spectroscopy, high-resolution electrospray ionization mass spectrometry, and X-ray diffraction.
