An infrared study of the stretching modes of the water molecules in ZnF2·4H2O

Synthesis and Complex Study of the Crystal Hydrate Zn2ZrF8·12H2O

“…11 Namely, the intensity of the band of asymmetric stretching vibrations of the Zr–F bond with the maximum at 482 cm –1 (T1u) in the IR spectrum increases (Figure 5c), whereas the band of symmetric stretching vibrations at 585 cm –1 (A1g) and those of bending vibrations with maxima at 264 (A1g) and 215 cm –1 (Eg) assigned to internal modes of the isolated [ZrF 6 ] 2– ion emerge in the Raman spectrum (Figure 6). In the IR spectrum of the formed product (85 °C), one can clearly distinguish an intensive band at 872 cm –1 (Figure 5c) related to the presence of ZnF 2 · 4H 2 O 26. Other bands characteristic of the IR spectrum of ZnF 2 · 4H 2 O are overlapped with those of ZnZrF 6 · 6H 2 O.…”
