We synthesized single-crystal TMTSF films from physical vapor deposition (PVD) of purified TMTSF powder. Two types of single crystals, needle and plate shaped, were obtained from a single PVD run. We identified from X-ray diffraction studies that the single-crystal films formed a flat surface with ab and ac planes for the needles and the plates, respectively. Interestingly, an identical triclinic stacking structure of TMTSF molecules in which the cell axes and angles were all different (i.e., a 6= b 6= c and α 6= β 6= γ) was found for both types of single crystals.
