Are there square planar complexes with sp2d hybridization?

We were taught (Under the section 'Valence Bond Theory') seven types of geometries a transition metal complex may assume and its corresponding hybridization states, Linear - $\ce{sp}$ Trigonal planar ...

Bond Lengths: Equatorial vs Axial in Trigonal Bipyramidal

Why is it that the axial bond length is less than equatorial bond length in $\ce{PF2Cl3}$ and $\ce{SF2Cl2}$ even though both have trigonal bi-pyramidal geometry? I know that in general axial bond ...

Bonding in hypervalent molecules

I don't know where they go the electrons of the extended-valence in molecules like $\ce{SF6}$ or $\ce{PCl5}$ for instance because my teacher said that the d orbitals can't interact with s and p (or ...

Bonding in Square Antiprismatic Compounds

Both $\ce{IF_8^-}$ and $\ce{XeF_8^{2-}}$ have (distorted) square antiprismatic geometries. I've been wondering how to explain the bonding in such compounds. Hypercoordinate bonding (as used to ...

Which species occupy the equatorial positions in VSEPR's trigonal bipyramidal and octahedral geometry

Which species (electronegative, double and triple bonded atoms, ions, lone pair etc.) occupy the equitorial position in the trigonal bipyramidal and octahedral geometry when we find the shape using ...

What is θ in Bent's rule equation (%s - character)?

I was learning about Bent's Rule. I came across a formula $$\cos\theta = \frac{s}{s-1}$$ I am quite confused about $\theta$. I know that it represents bond angle. But for a compound like $\ce{PCl5}$, ...

Structure of AsF3Cl2

Since the molecule has 5 bonding pairs and zero lone pairs, the shape should be trigonal bipyramidal. But one thing i am confused about is which atom(s) will occupy the axial and the planar positions, ...

Is ClH7 possible? [duplicate]

Chlorine can be $sp^3d^3$ hybridized. If so, it can form $\ce{ClH_7}$ and then chlorine, being more electronegative, will have (-7) as its oxidation number. But we know that the oxidation number of $\...

Structure of phosphorus pentachloride

Why is the shape of $\ce{PCl5}$ trigonal bipyramidal? All the $\ce{Cl}$ atoms must be at equal distances forming a star like shape. However, in the actual shape, the distance between the $\ce{Cl}$ ...

Would the lone pair be in the equatorial plane or the axial plane for bromine pentafluoride? [duplicate]

I've been learning chemical bonding and I'm confused about the structure of $\ce{BrF5}$. It has a square bipyramidal geometry but a square pyramidal shape - I got that. I don't get why the lone pair ...
