Abstract
The IR spectra (at 400–2000 cm−1) of chelate metal salts and mixed inorganic anhydrides of aminotriacetic acid (metalloatrane-3,7,10-triones) \(\begin{gathered} {\text{ | }} \downarrow \hfill \\ {\text{N(CH}}_{\text{2}} {\text{COO}})_3 {\text{M}} \hfill \\ \end{gathered} \) (M=B, Al, Ga, In, Tl, La, CeIII, NdIII, HOPbIV, ClZrIV, BiIII, CrIII, HOOMoVI, HOOUVI, FeIII, CoIII, and NiIII) and, for comparison, of compounds of the N(CH2COOM1)3 series (M1=H, Li, Na, K) were studied. The degree of ionic character and the character of the metal atom bond with the carboxyl groups was estimated on the basis of the high sensitivity of ν s and ν as (COO−), which are found at 1360–1450 and 1550–1630 cm−1, respectively, to structural changes in the molecules and from the presence of νC=O at 1710–1765 cm−1. The COO− bonds in compounds with M=CeIII, NdIII, ClZrIV, HOOMoVI, and NiIII are nonequivalent, which compels one to assign structure II with one free carboxyl group to them. The remaining investigated substances have the metalloatrane-3,7,10-trione structure, in which the degree of ionic character of the three equivalent M-O bonds varies over wide limits. The position of the νC-N absorption band at 1100–1130 cm−1 makes it possible to conclude that compounds with M=Fe, Co, Ni, Cr, Bi, ClZr, and HOPb contain the strongest M←N bond. The absorption maxima at 450–540, 540–560, and 570–640 cm−1 are presumably related to both the vibrations of the M←N bond and to the vibrations of the M-O bonds.
