Carbonato complexes coordination modes

The different types of coordination modes of carbonate in metal carbonato complexes offer challenges to investigate intimate mechanisms of their formation. The study of the kinetics and mechanisms of the formation and decomposition of such complexes, therefore, continue to be an interesting area of activity as it has a direct bearing on... 

Carbonate has proved to be a versatile ligand. Its coordination mode expands from 1 to 6, the last one is visualized when each atom binds two metal ions simultaneously. In recent years, significant progress has been made in the synthesis, structure, and magnetic properties of polynuclear carbonato complexes of transition metal ions. Such studies have also been extended to lanthanides and actinides. The speciation studies of these metal ions in aquatic environments in the presence of carbonate have resulted in significant... 

IR photodissociation spectra were reported for the clusters Al+(C02)n and Al+(C02)n.Ar, and compared with the results of ab initio calculations (all in the region of vasC02 modes).378 The complex (68), where R = 2,4,6-Ph3C6H2, has vCO at 1624 cm-1, compared to 1696 cm-1 in the free ligand, confirming the coordination shown.379 There is IR evidence for the formation of bi- and poly-dentate carbonato complexes by the adsorption of gaseous C02 on to (t-Ga203.380...
