We report a no. of 1:1 noncovalent complexes composed of a sym. trisphosphonate and various sym. trisammonium or trisamidinium compds. The spheroidal complexes show high thermodn. stability, with assocn. consts. Ka reaching 106 M-1 in methanol and in some cases even exceeding 103 M-1 in water. The obsd. Ka values correlate well with the different degree of preorganization of the complexation partners.
