Abstract

(formula presented) We report a number of 1:1 noncovalent complexes composed of a symmetrical trisphosphonate and various symmetrical trisammonium or trisamidinium compounds. The spheroidal complexes show high thermodynamic stability, with association constants K_a reaching 10⁶ M^-1 in methanol and in some cases even exceeding 10³ M^-1 in water. The observed K_a values correlate well with the different degree of preorganization of the complexation partners.
