Abstract

Abstract A bis (radical) derivative based on a triphenylphosphane core substituted by two nitronyl nitroxide units is reported. This compound was isolated in two forms. One consists of an H 2 O adduct where H 2 O is hydrogen-bonded to the radical units, whereas the second lacks this bridging unit. Magnetic studies revealed that the presence of the H 2 O bridge induces ferromagnetic exchange interaction between the spin carriers.(© Wiley-VCH ...
