By synchrotron X-ray diffraction measurement, we found that V trimerization occurs in various vanadates with V ions on quasi-triangular lattice, AV10O15(bilayer), A2V13O22(trilayer), and AV13O18(infinite layer), where A = Ba, Sr. We also found that this V trimerization substantially affects the electrical resistivity and magnetic susceptibility of these compounds. These results can be explained by the bond-ordered-type orbital ordering of V t2g states.
