The low-temperature (LT) superstructure of NaV2O5 was determined by synchrotron radiation X-ray diffraction. Below the phase transition temperature at 34 K, the LT structure is monoclinic. It was determined that the LT structure is (a - b) × 2b × 4c with the space group A112, where a, b and c represent the high-temperature orthorhombic unit cell. The valence estimation of V ions shows that the V sites are clearly separated into two groups of V4+ and V5+ with a zigzag charge-ordering pattern.
