Chemistry
Choose the most likely pattern for the crystal field diagram forthe complextrans–[Ni(NH3)2(CN)4]2–where CN– produces a much stronger crystal field thandoes NH3.?
From the answer the pattern show it is a square planer. Couldanyone explain it? why is not octahedral?

NiNH32CN42 shape as square planar can be considered as a special case of octahedral due to jahntellar distortion Here the oxidation state of Ni is 2 so the electronic configuration will be Ar 3d8 Now since 6 ligands are there they approach the metal cation along the cartesian coordinate axis Thus the eg orbitals viz 3dx2y2 and 3dz2 will have higher energy than the t2g orbitals viz dxy dyz and dzx It is bcoz
