Efficient Nickel-Catalyzed [2 + 2 + 2] Cycloaddition of CO2 and Diynes
... Carbon dioxide is an environmental friendly, nontoxic, nonflammable, and abundant resource.1 However, because its π orbitals are filled and relatively low in energy, the molecule is highly inert. Thus, the use of CO2 as a feedstock for forming new carboncarbon bonds remains a challenging goal for or ...

Coordination complex
In chemistry, a coordination complex or metal complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents. Many metal-containing compounds, especially those of transition metals, are coordination complexes.
