The crystal structure, thermal behaviour and ionic conductivity of a novel lithium gadolinium polyphosphate LiGd(PO3)4

Crystal structure and ion conductivity of a new mixed-anion phosphate LiMg3(PO4)P2O7

“…4b [34]. The conductivity and activation energy of LiMg 3 (PO 4 )P 2 O 7 are comparable to 1 7 those obtained for LiGd(PO 3 ) 4 , a condensed polyphosphate (σ = 2.5 × 10 -5 S cm -1 at 771 K, E a = 0.96 eV) that represents the Li···Li distances in the range 5.62-6.65 Å [35].…”

Structural Study of Europium Doped Gadolinium Polyphosphates LiGd(PO3)4 and Its Effect on Their Spectroscopic, Thermal, Magnetic, and Optical Properties

“…The obtained crystalline phases are isotypes of the mother-phase LiGd(PO 3 ) 4 [27]. Mainly, it is shown that XR diffraction peaks of studied solids, with different percentages of europium, are described in a cell with a super space group I 2/a instead of C 2/c usually used in crystallographic data of the old LGP.…”

“…Recently, our group reported compounds LiGd 5 P 2 O 13 which consists of isolated PO 4 tetrahedra linked with Ga polyhedra and Li + cations are located in the infinite tunnels, and K 3 Gd 5 (PO 4 ) 6 in which the structural units of Gd polyhedra and isolated PO 4 tetrahedra form a three-dimensional framework containing infinite tunnels in which the K + cations are located [7,8]. In addition, only several condensed polyphosphates containing Gd in ternary system have been reported [9][10][11][12][13][14][15]. For the type of MGd(PO 3 ) 4 compounds (M ¼ Na, K, Cs, and Ag), the basic structure units are helical ribbons (PO 3 ) n formed by cornersharing PO 4 tetrahedra.…”

“…Theses chains are joined to each other by GdO 8 dodecahedra, giving a threedimensional structure, with the M + cations located in framework tunnels [9][10][11][12][13]. The lattice of LiGd(PO 3 ) 4 is built of twisted zig-zag chains and make up of PO 4 tetrahedra sharing two corners, connected to the GdO 8 and LiO 4 polyhedra by common oxygen atoms to form a three-dimensional framework [14].…”
