45. For PhNIT, two independent molecules with differing atomic spin populations were found in the unit cell (see ref 44). The comparison is made with "molecule 2", in which the dihedral angle between nitronyl nitroxide and the phenyl ring, 29.8°, is similar to the value of 28.0° found in our system.
