Molecular Geometry: This is a comprehensive article comprising the definition and types of molecular geometry. It also explains the Valence Shell Electron Pair Repulsion (VSEPR) Theory in detail.
The molecule $\ce { [PdCl4]^2-}$ is diamagnetic, which indicates a square planar geometry as all eight d electrons are paired in the lower-energy orbitals. However, $\ce { [NiCl4]^2-}$ is also $\mathr...
CU Boulder News & Events: M330: Molecular Structures – VSEPR Theory – 6 Balloons
Six balloons tied together in a bunch arrange themselves in an octahedral fashion. As balloons are popped the resulting number conforms to the molecular shapes of VSEPR theory. To Conduct ...
Even though the molecule will have a structure that allows for it to exist in a planar conformation, there may be some/many that do not persist in a planar conformation due to steric effects, or complex three dimensional geometries.
Why is $\ce { (NH4)2 [CuCl4]}$ square planar complex but $\ce {Cs2 [CuCl4]}$ is tetrahedral even though both have same oxidation number of copper and same ligands?
inorganic chemistry - Why is (NH4)2 [CuCl4] square planar complex but ...
Why do square planar coordination compounds of type $\ce{[Mabcd]}$ not show optical activity, although they contain 4 different ligands (i.e. chiral central metal atom)?
It is not square planar but a Jahn-Teller distorted octahedron. You can check out its structure in the image below. You can fill electrons into the energy diagram in a standard fashion. You will arrive at the $\mathrm {d}_ {x^2-y^2}$ orbital for the unpaired electron — the one pointing towards the four ammine ligands.
Why is tetraamminecopper (II) a square planar and not a tetrahedral ...
