Query: Vanadium trimers randomly aligned along the c-axis direction in layered
  LiVO2   Herein, we discuss the identification of vanadium trimers in layered LiVO2
and its sulfide analog of LiVS2 with two-dimensional triangular lattices. Our
comprehensive structural studies using synchrotron X-ray diffraction
experiments clarified that vanadium trimers are randomly aligned along the
c-axis direction in LiVO2, while the long-range ordering of vanadium trimers
along the c-axis direction appears in LiVS2. Our results solve the longstanding
issue of cluster patterns in LiVO2 and provide an experimental basis for
identifying the mechanism of trimer formation.
