In chemistry, pentagonal pyramidal molecular geometry describes the shape of compounds where in six atoms or groups of atoms or ligands are arranged around a central atom, at the vertices of a pentagonal pyramid. It is one of the few molecular geometries with uneven bond angles.{{cite journal |doi=10.1016/j.jfluchem.2008.06.016 |title=Mean amplitudes of vibration of molecules and ions with interhalogen bonds and related species |date=2008 |last1=Baran |first1=Enrique J. |journal=Journal of Fluorine Chemistry |volume=129 |issue=11 |pages=1060–1072 |bibcode=2008JFluC.129.1060B }}
