PYRIDIN TYPE COMPLEXES OF TRANSITION-METAL-HALIDES .1. PREPARATION, CHARACTERIZATION AND THERMAL-ANALYSIS STUDIES OF COBALT(II)-CHLORIDES WITH 2,3,4-METHYLPYRIDINES

A large number of Co-picoline-chlorides were prepared from different reaction media by changing the Co: picoline molar ratio. A new solid-gas phase method is described to prepare ternary mixed Co-picoline complexes containing different picolines. According to the thermal and spectral investigations the ligand chemisorption from the vapour phase depends on the stability of the solid complex and the complex formation ability of the ligand in the gas phase.
