surface area measurements．The result indicated that HTlc-glutamate exhibited well-defined shape and obvious intercalated structure during the glycol-hydrothermal process. From the point of the model of anion coordination polyhedron growth units，the growth mechanism and morphology of the HTlc-glutamate was also studied. The result indicated that the growth morphology of HTlc-glutamate was consistent with the model. The HTlc-glutamate growth process included ① growth units incorporated to metal layers first

② metal layers adsorbed glutamate and H

③ growth units incorporated to layer compounds according. As a result

glycol played important role in bridging.
