When the total number of bonds and lone pairs is equal to seven, these are arranged in a pentagonal bipyramid to minimise repulsion between them. Note that VSEPR is quite poor at predicting the shapes of molecules with high coordination numbers and with central atoms from the bottom of the Periodic Table.
The shape of the molecule depends on the placement of the bonds. Click on the buttons to see how the possible shapes that result based on this arrangement.
