In case of [Ni(CO)4], the magnetic measurements show that the complex is diamagnetic in nature. So, instead of going for the dsp2 hybridisation, Ni2+ goes for sp3 hybridisation by forcing the electrons of 4s orbitals into the 3d-orbitals to pair up with the two unpaired d-electrons. Hence the complex is tetrahedral and diamagnetic.
