  • The crystal structure of amesite-2H1 from the Postmasburg Mn ores of South Africa has been refined to R = 4.7% using Siemens P4 rotating-anode MoKα X-ray data and SHELXL-93 software. Partial ordering of tetrahedral Si,Al and especially of octahedral Mg,Al has reduced the ideal P63cm symmetry to triclinic P1 (refined as C1). Tetrahedral rotation of 15° moves the basal oxygens toward the octahedral cations in the same layer but away from the OH H-donors of the next layers. The ordering pattern of AlIV and AlVI is unique in that the locus of Al-rich sites consists of 2 intersecting sets of zigzag lines parallel to X2 and X3, plus 2 Al-rich octahedra in layer 2 instead of the usual 1 site.

  • Summary

    This chapter shows how the Chinese commercial legal system has improved significantly over the past two decades, to the extent that in most cases it compares favorably in dispute resolutions outcomes with legal systems in most liberal democratic nations. However, it falls short of a "rule of law" system in certain types of cases due to three distortions interfering with decision-making by courts: political interference by local and sometimes central government officials; corruption; and guanxi (personal relationships) involving judges or senior court/government officials. The chapter uses the case of Judge Wang Linqing and the Shaanxi Billion Yuan Mining Rights dispute to demonstrate that these distorting elements have infected legal institutions right up to the Supreme People's Court and involve senior Chinese Communist Part leaders within China's anti-corruption agency and Politburo, making the problems very difficult to stamp out.
