| Dec 20, 2016 at 0:53 | comment | added | Jan | @InquisitiveMind $\ce{BrF5}$ should be composed of a standard 2e2c $\ce{Br-F}$ bond and two elongated 4e3c $\ce{F\bond{...}Br\bond{...}F}$ bonds (four-electron-three-centre bonds), giving it a square pyramidal structure with the central atom at the base of the pyramid. However, it probably fluctuates quickly between that and and the pentagonal bipyramid. In any case, remove d orbitals from your argumentation; they do not take part. | |

| Dec 19, 2016 at 14:47 | comment | added | Rodriguez | To be honest, I never run an ab initio valence bond calculation as described in that reference. I suggest someone interested in this topic, run an ab initio valence bond calculation. | |
| Dec 19, 2016 at 14:46 | comment | added | InquisitiveMind | Thats a good source , but what about BrF5 ? | |
| Dec 19, 2016 at 14:43 | comment | added | Rodriguez | Just a side quotation, depa.fquim.unam.mx/amyd/archivero/VBHIBRIDOSd_26401.pdf, "Figure 4. From a VB standpoint, the bonding in SF6 can be described using two, 2-electron bonds from sulfur sp hybrids pointing 180 away from each other and two, 2-electron bonds from sulfur p orbitals with the remaining four electrons located on two fluorine atoms" | |

| Dec 19, 2016 at 14:18 | comment | added | InquisitiveMind | No , not a homework problem . I myself was practicing by writing some compounds , my intuition says the above one is square pyramidal . When I searched a library book a different story was written there . | |
| Dec 19, 2016 at 14:14 | comment | added | Rodriguez | I mean, this question looks like an innocent homework assignment. But it is a complicated problem at the frontier of computational chemistry. | |
| Dec 19, 2016 at 14:13 | comment | added | InquisitiveMind | What dou you mean by "Morally justified" ? | |
| Dec 19, 2016 at 14:10 | comment | added | Rodriguez | I am wondering is this kind of question morally justified? Since the d orbital contribution is already deputable in hypervalent molecule such as, SF6 | |
