Metal coordination compounds

As metals only exist in solution as coordination complexes, it follows then that this class of compounds is useful in a wide variety of ways. In bioinorganic chemistry and bioorganometallic chemistry, coordination complexes serve either structural or catalytic functions. An estimated 30% of proteins contain metal ions. Examples include the intensely colored vitamin B12, the heme group in hemoglobin, the cytochromes, the chl… WebMetals are Lewis acids because of their positive charge. When dissolved in water, they react with water to form hydrated compounds such as Na(H 2O) + 6 and Cu(H 2O)2 + 6. These are called metal complexes, or coordination compounds. These …
