The IR spectra of thirty dicarboxylates of alkali-earth metal have been investigated. It was found that carboxylates of different metal ion have different coordinate structure. Chelate structure prevails in carboxylates of Mg, Sr and Ba. Both chelate structure and bridge structure appear in carboxylates of Ca and Zn. The kind of acid was found to have no effect on the coordinate structure of carboxylate. Through melting the sebacates different kinds of coordinate structure changes can be observed. The Mg salt changes from chelate to bridge and Ca salt becomes inter-molecular chelate form insteat of in-molecular bridge, the structure of Se and Ba salt keep same as before.
