The infrared and Raman spectra of the disodium salts of magnesium and calcium with adenosine 5'-triphosphate (ATP) along with the Be2+, Mg2+, Ca2+, Sr2+, and Ba2+ salts with H2ATP2- and Ca2+, Sr2+ and Ba2+ salts with ATP4- in the solid state are reported and the structural implications of these data considered. The infrared and Raman findings for the disodium salts of ATP with calcium and magnesium are in disagreement with earlier conclusions that ATP-4 is acting as a tetradentate ligand. Similarities among the spectra of all substances suggest that the group IIA cations interact mainly with the beta- and gamma-phosphates of ATP, in accordance with studies in aqueous solutions.
报道了镁和钙与腺苷5'-三磷酸（ATP）形成的二钠盐以及固态下Be2+、Mg2+、Ca2+、Sr2+和Ba2+与H2ATP2-形成的盐以及Ca2+、Sr2+和Ba2+与ATP4-形成的盐的红外光谱和拉曼光谱，并考虑了这些数据的结构意义。ATP与钙和镁形成的二钠盐的红外和拉曼研究结果与早期关于ATP-4作为四齿配体的结论不一致。所有物质光谱之间的相似性表明，根据水溶液中的研究，IIA族阳离子主要与ATP的β-和γ-磷酸基团相互作用。
