摘要：

An X-ray diffraction study of single-crystal CO2 has been undertaken at 1.00 (5) GPa pressure. The crystal exhibits Pa (3) over bar symmetry with a cell edge of 5.4942 (2) Angstrom and a C-O bond length of 1.168 (1) Angstrom (corrected for thermal motion effects). The study demonstrates that an earlier claim of a new dry ice II phase at this pressure is unfounded.
