Abstract The crystal of a new ambient-pressure superconductor, κ-(BEDT-TTF)2I3 belongs to the monoclinic system with space group P21/c and a=16.387, b=8.466, c=12.832 Å and β=108.56°. The 2-dimensional(2D) metal sheets composed of paired BEDT-TTF molecules and the I3 anion sheets are arranged alternately along the a. direction. The orientation of the neighbouring paired molecules is almost perpendicular to each other.
