WebChemotrophs are organisms that obtain energy through the oxidation of electron donors in their environments. These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which utilize solar energy. Chemotrophs can be either autotrophic or heterotrophic. Web3 Jun 2024 · The third kind of metal-ligand π-bonding occurs when a π-donor ligand - an element with both a σ-symmetry electron pair and a filled orthogonal p-orbital - bonds to a metal, as shown above at the right for an O 2- ligand. This occurs in early transition metal complexes. In this example, O2- is acting as both a σ-donor and a π-donor.
