Following earlier theoretical work on a candidate hormone bonded with the Ru complex NAMI-A, here, we begin an extension to involve the ligand oestradiol. In particular, we shall compare and contrast the ground-state inhomogeneous electron liquid in oestradiol with that in the closely related hormone; oestrone. Both these systems are studied quantum-chemically at the level of restricted Hartree-Fock theory (RHF). In each case, the equilibrium geometries are recorded in tabular form. The sum of the RHF-occupied eigenvalues is related to the ground-state energy of the electron liquid in each case. Finally, a brief qualitative discussion is added of the way the ligand oestradiol can cause dimerisation of oestrogen receptors and its likely interest for cell biology and for human breast cancer.
