%X Molecular addition complexes of the type CoL2X2 (X = Cl, Br, I and L = 2-aminothiazole and 2-acetylaminothiazole) have been prepared and studied by infrared spectra, electronic spectra, magnetic susceptibility and X-ray powder data. Infrared and electronic spectra suggest coordination through exocyclic nitrogen in 2-aminothiazole and through carbonyl oxygen in 2-acetylaminothiazole. The complexes have tetrahedral configuration and belong to the C2&quot; point group. Ligand field parameters Dq, B' and &#946; show more covalency in 2-aminothiazole complexes than in 2-acetylamino-thiazole complexes and suggest a weak ligand field for both the ligands.
