title: Highly repulsive interaction in novel inclusion D2-N2 compound at high pressure: Raman and x-ray evidence.
abstract: We present spectral and structural evidences for the formation of a homogeneous cubic δ-N(2)-like, noncrystalline solid and an incommensuratelike hexagonal (P6(3)22) inclusion compound (N(2))(12)D(2), formed by compressing a nitrogen-rich mixture to 5.5 and 10 GPa, respectively. A strong repulsive coupling in (N(2))(12)D(2) is evident from a blue shift, discontinuous changes, and the absence of turnover of the D(2) vibron to 70 GPa--all in sharp contrast to both pure D(2) and other inclusion compounds. This repulsive interaction is responsible to the observed incommensuratelike structure and large internal pressure.
