Inorganic Chemistry Lecture Material A noticeable difference between chromium(III) and cobalt(III) chemistry is that cobalt complexes are much less susceptible to hydrolysis, though limited hydrolysis, leading to polynuclear cobaltammines with bridging OH- groups, is well known.

The peripheries of the selected complexes bear three trigonally directed substituents known to engage in various intermolecular interactions, including COOH, CN, diaminotriazinyl (DAT), and Br. To allow comparison, structures were determined for both racemic and enantiomerically pure complexes in all cases,

Two isomers of the methyl derivative [MeCoIII(L1NHpy)(H-L1NHpy)]+ were isolated. The X-ray analysis reveals that these isomers differ from one another in configuration of the C and N chiral centers. Possible reaction mechanisms leading to these different types of complexes are proposed.
