Synthesis and spectroscopic characterization of palladium(II) complexes with 6,8-dimethylimidazo[1,5-a]-1,3,5-triazin-4(3H)-one and 6,8-dimethyl-2-thioxo-2,3-dihydroimidazo-[1,5-a]-1,3,5-triazin-4(1H)-one

Abstract

The preparation and spectroscopic study (1H, 13C, 15NNMR, 13CP MAS NMR, IR) of new PdII complexes with 6,8-dimethylimidazo[1,5-a]-1,3,5-triazin-4(3H)-one (6,8-DiMe-4-O-IMT) (1) and 6,8-dimethyl-2-thioxo-2,3-dihydroimidazo[1,5-a]-1,3,5-triazin-4(1H)-one (6,8-DiMe-4-O-2-S-IMT) (2) is reported. The spectroscopic data indicate a square planar geometry with two N(7) bonded heterocycles and two cis-chloride anions. The final product of the thermal decomposition of cis-PdCl2(6,8-DiMe-4-O-IMT)2 (3) is metallic Pd, whereas for cis-PdCl2(6,8-DiMe-4-O-2-S-IMT)2 (4) it is metallic Pd plus C.
