title: A new carbon phase constructed by long-range ordered carbon clusters from compressing C70 solvates.
abstract: An ordered amorphous carbon cluster (OACC) structure with building blocks of highly deformed/collapsed C70 is synthesized by compressing C70 *m-xylene, which exhibits an exceptionally high hardness. Different from compressing C60 *m-xylene, a new structure transition is observed in C70*m-xylene at above 30 GPa, indicating the formation of a new OACC structure under pressure.
