Summary

New complex salts of lanthanide chlorides with hexamethylenetramine of the general formulaLnCl3·2HMTA·nH2O [Ln=La, Pr, Nd, Sm, Dy, Er;HMTA-hexamethylenetetramine N4(CH2)6;n=8, 10, 12] have been obtained. On the basis of IR IR spectra (4000-200cm−1) and Raman spectra (3000-300 cm−1), changes in the coordination sphere structure of the salts occurring in the course of thermal dehydration have been determined.

Zusammenfassung

Neue Komplexsalze der Lanthanidchloride mit Hexamethylentetramin mit der allgemeinen FormelLnCl3·2HMTA·nH2O [Ln=La, Pr, Nd, Sm, Dy, Er;HMTA — Hexamethylentetramin N4(CH2)6;n=8, 10, 12] wurden dargestellt. Die Änderungen in der Struktur der Koordinationssphäre während der thermischen Dehydration der Salze wurden mittels Infrarot-(4 000–200 cm−1) und Ramanspektroskopie (3 000–300 cm) bestimmt.
