(PPh4)(2)[NiCl4]. 2MeCN (space group l (4) over bar, a=1839.3 pm, c=1375.3 pm) has a crystal packing derived from the BiPh4[ClO4] structure type with a fourfold increased unit cell and one half of the ClO4- positions substituted by pairs of acetonitrile molecules. The crystal ...
[NiCl_4]^(2-) paramagnetic but [Ni(CO)_4] diamagnetic though both are tetrahedral in shape. Explain why? View Solution Explain on the basis of valence bond theory that [Ni(CN)4]2− ion with square planar structure is diamagnetic and the [NiCl4]2− ion with tetrahedral geometry is...
