Low temperature X-ray diffraction study for organic semiconductor (BEDT-TTF)3CuBr4 revealed structural phase transition from P21/c to Pc by losing inversion and screw symmetries at 60.2 K where the magnetic susceptibility shows a steep decrease. Abrupt changes in (0 k 0) X-ray reflection intensity and lattice parameters proved that this phase transition has first-order nature. Structure analysis at 65.9 K verified that the average coordination number of Br around Cu is four.
