Recently, there has been a lot of discussion of Bent's rule (see for example "What is Bent's rule?") here in SE Chem. The spectra of PCl4F are best interpreted in terms of a C3v structure in which the fluorine atom occupies an axial site; in PCl3F2 (D 3h point group) the fluorine atoms also assume axial positions. There is sp3d (Sp2+pd) hybridization trigonal bipiramidal(TBP) geometry in PCl 3 F 2 molecule. In chemistry, a trigonal bipyramid formation is a molecular geometry with one atom at the center and 5 more atoms at the corners of a triangular bipyramid.This is one geometry for which the bond angles surrounding the central atom are not identical (see also pentagonal bipyramid), because there is no geometrical arrangement with five terminal atoms in equivalent positions. The less intuitive, but more accurate, process would be to realize that the structure of the molecule is divisible into two non-polar structures (trigonal planar and linear). There is free rotation about the carbon-to-carbon single bonds (C–C) in alkanes. All of the compounds appear to have a basic trigonal bipyramidal framework. Hybridization: sp 3 d Then draw the 3D molecular structure using VSEPR rules: Don't put the chlorine atoms directly across from each other; the fluorine atoms are more electronegative … here in SE Chem. Simply stated, the rule suggests that $\mathrm{p}$-character tends to concentrate in orbitals directed at electronegative elements.Why does $\ce{F}$ replace an axial bond in $\ce{PCl5}$?.
