This method builds the nickel tetracarbonyl structure up from nothing by using the Symmetry Toolkit to create an irreducible fragment of unique atoms in the desired symmetry. [10] The monosubstitution of nickel tetracarbonyl with other ligands can be used to determine the Tolman electronic parameter, a measure of the electron donating or withdrawing ability of a given ligand. Thus, treatment of Ni(CO)4 with carbon nucleophiles (Nu−) results in acyl derivatives such as [Ni(CO)3C(O)Nu)]−.[11]. The CO ligands, in which the C and the O are connected by triple bonds, are covalently bonded to the nickel atom via the carbon ends. Thus, donor ligands such as triphenylphosphine react to give Ni(CO)3(PPh3) and Ni(CO)2(PPh3)2. The molecule is tetrahedral, with four carbonyl (carbon monoxide) ligands.
