Structural investigations of several LnVO4 compounds

Electronic, elastic and optical properties of zircon GdVO4 investigated from experiments and LSDA+U

“…The optimized lattice parameters and experimental values for GdVO 4 are listed in Table 1. From Table 1, we can see that the deviation of lattice parameters and the value for u and v between theoretical value and experiments is less than 2%, so the results we got from calculations are in good agreement with our experimental results and other experiment data reported by Donald et al [26].…”

“…1 shows the crystal structure of zircon-type GdVO 4 in space group I4 1 /amd. For zircon structure AVO 4 , the A atoms located at the Wyckoff position 4a (0, 0.75, 0.125), the V atoms at 4b (0, 0.25, 0.375), and the O atoms at 16 h (0, u, v) [26]. For zircon-type AVO 4 , the key factor which determines the crystal structure is the site of O.…”

Vanadium‐Catalysed Aerobic Cleavage of C−C Bonds in Substituted Cyclohexanones To Afford Carboxylic Acids: Two Model Complexes with Tetrahedral Geometry around Vanadium(V)

“…[31,32] This structural motif is typically found in orthovanadates such as LiMnVO 4 [33] and LnVO 4 . [34] The [V 4 O 12 ] 4Ϫ ion has a cyclic tetrametaphosphate-like structure with an Ot-V-Ot angle of only 102.3(1)°, [35] the three others being 111°, while [V 5 O 14 ] 3Ϫ is pentanuclear with OϪVϪO angles ranging from 107.6(4) to 112.7(3)°. [36] In 4b, the tetraphenyl phosphonium cations are well behaved and have the expected dimensions.…”

Hydrothermal synthesis and structural study of lanthanide orthovanadates, LnVO4 (Ln=Sm, Gd, Dy and Ho)

“…Among the binary system Ln 2 O 3 -V 2 O 5 , tetragonal orthovanadates, LnVO 4 are synthesized at higher temperatures and are structurally characterized by powder X-ray diffraction as well as single crystal X-ray diffraction analysis [1][2][3][4][5][6]. Since these solids are potential catalysts for the oxidative dehydrogenation of propane, several attempts have been made to prepare these at relatively lower temperatures either by solid-state reaction or precursor routes [7][8][9].…”
