N1 - Funding Information:
We would like to thank H. Sawa and T. Yokoo (KEK) for their interest in this work and for fruitful discussion. Aoyama-Gakuin group was partly supported by 21st COE program. The synchrotron radiation experiments were performed at the BL46XU (R04B46XU-0020N) in the SPring-8 with the approval of the Japan Synchrotron Radiation Research Institute (JASRI). A part of electron diffraction was supported by “Nanotechnology Support Project” of the MEXT, Japan.

N2 - We report here on the observation of superlattice reflections in the new quasi-one-dimensional spin system TiOBr by electron and synchrotron radiation X-ray diffractions. We discussed on crystal symmetry and temperature dependence of superlattice reflections. Superlattice reflections can be observed at ( h, k + frac(1, 2), 0) below Tc 1 and ( h ± δh, k ± δk, 0) above Tc 1; ( h + k = 2 n ). We discussed the origin of two phase transitions, Tc 1 ( = 27 K ) and Tc 2 ( = 47 K ) in TiOBr.
