Palladium(II) and platinum(II) chloride and bromide complexes with some 2-methylpyridyl- or methylquinolyl-benzimidazole,benzoxazole, or benzthiazole

Summary Palladium(II) and platinum(II) complexes MLX₂], where L=2-(4-methyl-2-pyridyl)benzimidazole (mpbi), 2-(4-methyl-2-pyridyl)benzoxazole (mpbo), 2-(4-methyl-2-quinolyl)benzoxazole (mpbo), 2-(4-methyl-8-quinolyl)benzoxazole (mq'bo), X=Cl. Br, together with M(mqbo)₂Br₂ and Pt₂(mpbt)Cl₄, where mpbt=2-(4-methyl-2-pyridyl)benzthiazole, have been synthesized and characterized by conductivity and magnetic measurements as well as by i.r. and electronic spectra. The ligands are bidentate chelates through the pyridine or quinoline and isoxazole or imidazole nitrogen atoms. The MLX₂] derivatives arecis, square planar.
