Answer to Question #44604 in Inorganic Chemistry for Alisha

Question #44604
I have some doubts in coordination compounds. Well I was making the structure of [Ni(CN)4]2- and lost my mind. If we work according to the crystal field theory then (Ni)2+ is d8 configuration which means it will have 2 unpaired electrons in the t2 orbitals. While if we work according to the valence bond theory then the 2 unpaired electrons of Ni2+ have to pair up in presence of strong ligand CN- meaning there are no unpaired electrons. How is this possible? Which is correct? Sorry for my poor English. Hope you reply soon :)
