The lattice parameter a of fullerite C-60 intercalated with N-2 molecules is investigated in the temperature interval 6-295 K by x-ray diffraction. It is found that the interstitial molecular N-2 has a considerable effect on both the orientational phase transition temperature T-c and the orientational glass formation temperature T-g. Hysteresis of a(T) in the T-c and T-g regions is detected, along with an abrupt change in volume over the region defining T-c. Complete intercalation of C-60 with N-2 molecules results in a 0.2% increase in the lattice parameter, which persists over the whole temperature range. Evidence is also obtained that the interstitial guest molecular N-2 induces a slight deformation of the cubic symmetry of the C-60 host lattice.
