... How does the bonding in the complex [NiCl4]2– differ from the bonding in CCl4? In CCl4, the C-Cl bonds are polar covalent; each involves the sharing of 1 electron from C and 1 electron from Cl to make a 2 electron bond. In [NiCl4]2-, the Ni-Cl bonds also involve 2 electrons. However, both originate ...

Metal carbonyl
Metal carbonyls are coordination complexes of transition metals with carbon monoxide ligands. Metal carbonyls are useful in organic synthesis and as catalysts or catalyst precursors in homogeneous catalysis, such as hydroformylation and Reppe chemistry. In the Mond process, nickel carbonyl is used to produce pure nickel. In organometallic chemistry, metal carbonyls serve as precursors for the preparation of other organometalic complexes.Metal carbonyls are toxic by skin contact, inhalation or ingestion, in part because of their ability to carbonylate hemoglobin to give carboxyhemoglobin, which prevents the binding of O2.
