Both [Ni(CO)4] and [Ni(CN)4]2– are diamagnetic. The hybridisations of nickel in these complexes, respectively, are
sp3, sp3
sp3, dsp2
dsp2, sp3
dsp2, dsp2
Both complexes – [Ni (CO)4] & [Ni (CN)4]2– have strong field ligand which causes pairing of electrons in 3d-orbitals but the O.N. of Ni in [Ni(CN)4]2– = + 2, While in [Ni(CO)4] is '0' Hence hybridizations of Ni are respectively sp3 & dsp2
