“…The deuterated sample of iron fluoridotinanate (DITF) with the idealized formula

{FeTiF}_{6} \cdot 6 {normalD}_{2} normalO

was produced by triple recrystallization of hydrated iron fluoridotinanate (HITF) from heavy water (99.8% D 2 O). The synthesis of the initial HITF was described in our previous publication, [19] and the real composition of the crystals corresponded to the formula Fe 0.9 Ti 1.1 (OH) 0.5 F

_{5.7} \cdot 5.8 H_{2} normalO

[20] ; 80 g of these crystals and 60 ml of heavy water were placed in a Teflon tube with a tightly closed stopper and heated in a beaker with boiling water to completely dissolve the crystals. After that, the solution was cooled in a refrigerator, and the crystals weighing about 40 g precipitated and were filtered in a dry box filled with argon.…”

Phase transition in FeTiF 6 Á xH 2 O Á yD 2 O crystals has been studied by Raman spectroscopy. The 611 cm À1 line corresponding to mode A 1g of ½TiF 6 2À system does not exhibit anomalous behavior associated with the phase transition. The temperature studies showed that below the phase transition temperature, the equivalence of D 2 O molecules in FeTiF 6 Á xH 2 O Á yD 2 O octahedron is broken.The phase transition mechanism in the compound under study is associated with FeðxH 2 O Á yD 2 OÞ complex.

The magnetic properties of fluorine hexahydrates of transition metals have been studied. It was found that the presence of spin-orbit interaction of the transition metal ion has a significant effect on anisotropy of magnetic properties. Depending on the direction of interaction of the orbital magnetic moment of a transition metal cation with a crystal field easy direction of magnetization changes from the crystallographic b-axis to the c-axis. Keywords: single crystal, magnetic anisotropy, Jahn-Teller effect.
