Abstract: Molecular Modelling of “spherical” cyclophosphazenic dandelion dendrimers shows that the whole moieties belong to the C3 point group, conversely to the starting material, N3P3Cl6, which is of D3h symmetry. Moreover, these spherical dendrimers actually have significant dipole moments due to a non-centrosymmetrical distribution of the lone pairs of the nitrogen atoms of their amino groups and functions.
