In this complex, central nickel atom is attached to four CO ligands. The oxidation state of nickel is zero. Nickel atom has the configuration 3d84s². In the presence of strong CO ligands, rearrangement takes place and the 4s electrons are forced to go into 3d orbitals. Thus, Ni can now provide 4s- and 4p- orbitals for hybridisation. One 4s- and three 4p- orbitals undergo sp³ hybridisation and form four hybrid orbitals of equal energy which are directed towards the four corners of a regular tetrahedron. These orbitals overlap with orbitals of CO ligands. Thus, a tetrahedral [Ni(CO)4] complex is formed.
