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.Tue, 07 Apr 2026 03:31:00 GMThttps://chemistry.stackexchange.com/questions/40880/why-is-pdcl42-square-planar-whereas-nicl42-is-tetrahedralThe 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 $\mathrm {d^8}$ but has two unpaired electrons, indicating a tetrahedral geometry.Mon, 06 Apr 2026 16:04:00 GMThttps://chemistry.stackexchange.com/questions/4649/how-to-use-crystal-field-theory-to-predict-whether-a-complex-ion-with-coordinatiHow can one predict whether a given complex ion will be square planar or tetrahedral when its coordination number is 4 using crystal field theory? Is it possible to theoretically predict this?Thu, 02 Apr 2026 08:23:00 GMThttps://chemistry.stackexchange.com/questions/133751/why-is-dinitrogen-tetroxide-a-planar-moleculeI was wondering why $\\ce{N2O4}$ is a planar species in spite of having a σ-bond in between the two $\\ce{N}$ atoms for free rotation. Does it not form a conformer?Sat, 04 Apr 2026 03:56:00 GMThttps://chemistry.stackexchange.com/questions/133794/why-is-the-crystal-field-splitting-energy-larger-for-square-planar-than-octahedr1 It is because of the fact that square planar complexes are formed by much strong ligands with d8-metal cation of 3d- series transition metals cation and 4d or 5d-series transition metal cation with either weak or strong ligands. The very strong ligands and 4d or 5d-series transition metal cations are responsible for higher crystal field ...Tue, 31 Mar 2026 16:04:00 GMThttps://chemistry.stackexchange.com/questions/19857/why-are-square-planar-coordination-compounds-with-four-different-ligands-opticalWhy 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)?Mon, 30 Mar 2026 14:46:00 GMThttps://chemistry.stackexchange.com/questions/181972/does-cobalt-form-square-planar-complexesTechnically, square planar cobalt complexes can be formed with specially designed carbene ligands [1]. Such species may serve as catalysts for electron-transfer processes.Mon, 06 Apr 2026 07:14:00 GMThttps://chemistry.stackexchange.com/questions/43111/jahn-teller-distortions-in-square-planar-complexesA Jahn-Teller distortion is predicted whenever a non-linear symmetric molecule has degenerate orbitals and has unequal electron occupation in those degenerate orbitals. Of course, this most often isSat, 04 Apr 2026 06:33:00 GMThttps://chemistry.stackexchange.com/questions/185243/which-diagram-for-crystal-field-splitting-of-square-planar-is-accurateI have come across these two splitting. Which of these is correct when there is crystal field splitting of ligand in square planar manner. Kindly provide reference of books and plausible explanatio...Wed, 25 Mar 2026 08:04:00 GMThttps://chemistry.stackexchange.com/questions/34329/why-is-tetraamminecopperii-a-square-planar-and-not-a-tetrahedral-speciesIt 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.Sat, 04 Apr 2026 09:18:00 GMT
