Talk:Trigonal bipyramidal molecular geometry

plx help!!!!

In PCl5, why can't the 4s orbitals be used in the "hybirdization"? Why is the hybridization of P in the compound as sp3d, but not s2p3( using a 3s, a 4s, 3 3p orbitals)?

What is mean by the statement: there is a conflict between 3s and 4s in the hybridization?

thx

Suggested move....
Shouldn't this be at 'Trigonal Bipyramidal molecular geometry'? Chris (talk) 22:57, 19 January 2008 (UTC)

P.S. Not sure about the infobox either.

Angles
Is 180 supposed to be one of the angles? JustWeamy (talk) 09:51, 1 August 2016 (UTC)
 * Opinions differ on whether to include the 180° angle, which refers to the angle between the two axial bonds. Many authors exclude 180° and consider only the angles between "nearest-neighbor" bonds which are 90° and 120°. For example Housecroft + Sharpe, Inorganic Chemistry 2nd ed. p.46; Miessler and Tarr, Inorganic Chemistry p.56; Petrucci et al. General Chemistry 8th ed. p.413. But some do add 180° because there are two (axial) bonds separated by that angle. For example, Whitten et al. General Chemistry 4th ed. p.301.
 * Also the same difference of opinion occurs for the octahedral molecular geometry, for which most authors just include 90° but some such as Whitten add 180°. Dirac66 (talk) 01:48, 2 August 2016 (UTC)

Seemingly another example of this with nitrogen and gold.
Not a chemist, but read an article mentioning this molecular geometry in a compound made from Tetrakis.
