May be hypervalent but has no d functions

WebAnswer (1 of 5): A hypervalent molecule is a molecule that contains one or more main group elements apparently bearing more than eight electrons in their valence shells. … Hexacoordinate phosphorus molecules involving nitrogen, oxygen, or sulfur ligands provide examples of Lewis acid-Lewis base hexacoordination. For the two similar complexes shown below, the length of the C–P bond increases with decreasing length of the N–P bond; the strength of the C–P bond decreases with increasing strength of the N–P Lewis acid–Lewis base interaction.
