Abstract:

The coordination mode between organic functional groups and inorganic metal of layered hybrid materials M₂(OH) _(4-x) (C₁₀H₁₇O₂)x·zH₂O, synthesized by grafting of chiral 3,7-dimethyl-6-Octenoic acid in layered hydroxide metal acetates, was analyzed and discussed using infrared spectroscopy (IR) technology. The results showed that the carboxyl functional groups in the organic-inorganic hybrid material M₂(OH) _(4-x) (C₁₀H₁₇O₂)x·zH₂O took a bidentate coordination mode, one end of the carboxyl functional groups connected to the inorganic metal ion, the other one end of it bonded the hydroxyl or water by hydrogen bonds.
 

Key words: layered compound; hybrid material; coordination mode
