Abstract:

The first examples of bismuth fluoride selenites with d 0 -TM/Te VI polyhedrons, namely, Bi 4 TiO 2 F 4 (SeO 3 ) 4 (1), Bi 4 NbO 3 F 3 (SeO 3 ) 4 (2), Bi 4 TeO 4 F 2 (TeO 3 ) 2 (SeO 3 ) 2 (3), Bi 2 F 2 (MoO 4 )(SeO 3 ) (4) and Bi 2 ZrO 2 F 2 (SeO 3 ) 2 (5) have been successfully synthesized under hydrothermal reactions by aliovalent substitution. The five new compounds feature three different types of structures. Compounds 1–3, containing Ti IV , Nb V and Te VI respectively, are isostructural, exhibiting a new 3D framework composed of a 3D bismuth oxyfluoride architecture, with intersecting tunnels occupied by d 0 -TM/Te VI octahedrons and selenite/tellurite groups. Interestingly, compound Bi 4 TeO 4 F 2 (TeO 3 ) 2 (SeO 3 ) 2 (3) is the first structure containing Se IV and mixed-valent Te IV /Te VI cations simultaneously. Compound 4 features a new 3D structure formed by a 3D bismuth oxyfluoride network with MoO 4 tetrahedrons and selenites groups imbedded in the 1D tunnels. Compound 5 displays a novel pillar-layered 3D open framework, consisting of 2D bismuth oxide layers bridged by the [ZrO 2 F 2 (SeO 3 ) 2 ] 6− polyanions. Theoretical calculations revealed that the five compounds displayed very strong birefringence. The birefringence values of compounds 1–3, especially, are above 0.19 at 1064 nm, which are larger than the mineral calcite. Based on the structure and property analysis, it was found that the asymmetric SeO 3 groups (and TeO 3 in compound 3) displayed the largest anisotropy, compared with the bismuth cations and the d 0 -TM/Te polyhedra, which is beneficial to the birefringence. © 2019 Wiley-VCH Verlag GmbH & Co.
