11. A non-polar diluent favours the formation of uncharged non-polar metal complexes . 12. Octahedral transition-metal complexes containing amines and simple anions are often referred to Werner-type complexes. 13. While at Columbia she began studying transition-metal complexes and their possible applications to chemotherapy. 14. Transition metal complexes are generally bound by coordinate covalent bonds. 15. It will also act as a ligand in metal complexes , and can be reduced. 16. To generate the metal complex , two common routes are employed. 17. Triphenylsiloxide is a common derivative useful for generating metal complexes . 18. Hexafluoroacetylacetonate is also widely used to generate volatile metal complexes . 19. Chiral ligands confer chirality to a metal complex , as illustrated by metal-amino acid complexes. 20. Many reactions of octahedral transition metal complexes occur in water.
