WebIn many cases these homoatomic species are not fairly isolated in the structures but make use of their paired or unpaired p-electrons and, if available, of their π-systems to establish (strong) heteropolar covalent donor bonds to metal cations. Such coordination can have retroactive effect on the bonding inside the ligand and even stabilises ... WebMetal ions are indispensable to biological function, as they are utilized for a myriad of processes encompassing signaling, electron transfer, and catalysis. These functions are made possible by exploiting intrinsic properties of the metal ions and the ligands to which they bind, represented by small molecules and metalloproteins.
