This octahedral geometry arises due to d 2 s p 3 or s p 3 d 2 hybridisation of the central metal atom or ion. The octahedral shape looks like two pyramids with four sides each that have been stuck together by their bases. S 2 : In S F 4 the bond angles, instead of being 9 0 ∘ and 1 8 0 ∘ are 8 9 ∘ a n d 1 7 7 ∘ respectively due to the repulsions between lone pair and bond pairs of electrons. What is the hybridization of the central atom in XeF2? We can imagine the platinum at the middle with the six fluorines at each of the vertices of the pyramids. Hybridization = What are the approximate bond angles in this substance? What is the hybridization of the central atom in IF? But all the $\mathrm{3d}$ orbitals are already populated, so where do the two $\mathrm{d}$ orbitals come from? Octahedral complexes in which the central atom is d2sp3 hybridised are called inner- orbital octahedral complexes while the octahedral complexes in which the central atom is sp3d2 hybridised are called outer orbital octahedral. The $\mathrm{4d}$ set, I suppose.. Moving on to $\ce{Ni(II)}$ octahedral complexes, like $\ce{[Ni(H2O)6]^2+}$, the typical explanation is that there is $\mathrm{sp^3d^2}$ hybridisation. To have the octahedral shape, a molecule must have a central atom and six constituents. That is, the metal ions , Co 2+ ,Ni 2+ ,Cu 2+ and Zn 2+ show sp3d 2 hybridization … A. Because, all the above said ions contain seven or more electrons in their inner 3d-orbital.Hence, in the formation of octahedral complexes, they can’t attain d 2 sp 3 hybridization. Octahedral geometry can lead to 2. The shape of the orbitals is octahedral.Two orbitals contain lone pairs of electrons on opposite sides of the central atom. NOTES: This molecule is made up of 6 equally spaced sp 3 d 2 hybrid orbitals arranged at 90 o angles. Octahedral - $\ce{d^2sp^3}$ or $\ce{sp^3d^2}$ - the hybridization of one $\ce{s}$, three $\ce{p}$, and two $\ce{d}$ orbitals produce six hybrid orbitals oriented toward the points of … (ii) [Ni(CO) 4 ] has sp3 hybridization, tetrahedral shape. The hybridisation in octahedral complexes are d 2 s p 3 or s p 3 d 2. Octahedral geometry arises due to d2sp3 or sp3d2 hybridisation of the central metal atom or ion. The shape of the orbitals is octahedral.Since there is an atom at the end of each orbital, the shape of the molecule is also octahedral.. Back to top (a) (i) [FeF 6]3_ has sp3d2 hybridization, octahedral shape. S 3 : Aqueous H 3 P O 4 is syrupy (i.e more viscous than water). All the complex ions having a coordination number of central metal atom as six show octahedral geometry. Hybridization What are the approximate bond angles in this substance Bond angles = B. Octahedral complexes. The points raised above for tetrahedral case above still apply here. (b) CO forms more stable complex than CN- because it can form both a as well as n-bond with central metal atom or ion. coordination compounds class 12 is a complex subject and a lot of theory is there in it.
