Using X-ray and DAC, room-temperature crystal structures under physical pressure (PP) were solved for DCNQI-Cu compounds which exhibit particular metal-insulator (M-I) transition owing to their electronic low dimensionality (CDW) and strong correlation (Mott). This M-I transition is known to be triggered with moderate (=small) PP or chemical substitution (chemical pressure:CP). Observed high pressure structures were compared with theoretical structure determinations. From the structural viewpoint, relation between PP and CP effects on the M-I transition was discussed.
