A table of geometries using the VSEPR theory can facilitate drawing and understanding … Thus, the bond angles of the atoms are 180 degrees from each other. (AX4E in AXE notation) An atom bonded to 5 other atoms (and no lone pairs) forms a trigonal bipyramid; but in this case one of the atoms is replaced by a lone pair. The seesaw shape maximizes the bond angles of the single lone pair and the other atoms in the molecule. Structure The geometry of molecule of BF3 is 'Trigonal Planar. ' The axial fluorides are not quite at 180 o to each other, and the remaining equatorial fluorides are at slightly less than 120 o to each other. Compounds with seesaw geometry have two types of ligands, one pair related by 180° often called axial ligands. Molecular structure, which refers only to the placement of atoms in a molecule and not the electrons, is equivalent to electron-pair geometry only when there are no lone electron pairs around the central atom.
