چکیده
The two hitherto unknown lithium holmium(III) ortho-thiophosphates(V) Li9Ho2[PS4]5 and Li15Ho7[PS4]12 crystallize in the monoclinic space group C2/c with lattice parameters a=1489.43(9) pm, b=979.84(6) c=2051.68(12) ?=96.221(3)° for (Z=4) a=2826.73(16) b=1003.25(6) c=3361.46(19) ?=113.992(3)° (Z=5). While extends Li9RE2[PS4]5 series, can be regarded as a cation-distribution variant of Li6RE3[PS4]5 series (Z=12). Both structures feature characteristic [HoS8]13? polyhedra (d(Ho3+?S2?)=275–314 pm) [PS4]3? tetrahedra (d(P5+?S2?)=202–207 pm), but exhibits one Ho3+ position, which is mixed occupied Li+ settles C.N.=6+2. coordination numbers all other cations range from four to six both new compounds Li+?S2? distances 238 317 pm.

Lithium vanado(V)molybdate(VI), Li[VMoO6]
Brannerite-type Li[VMoO6] has been synthesized by a solid state reaction route. The V and Mo atoms statistically occupy the same site with mirror symmetry and are octa-hedrally surrounded by O atoms. The framework is two-dimensional and is built up from edge-sharing (V,Mo)O6 octa-hedra forming (VMoO6)∞ layers that run parallel to the (001) plane. Li(+) ions are situated in position with symmetr...
متن کامل(7)Li NMR and two-dimensional exchange study of lithium dynamics in monoclinic Li(3)V(2)(PO(4))(3).
High-resolution solid-state (7)Li NMR was used to characterize the structure and dynamics of lithium ion transport in monoclinic Li(3)V(2)(PO(4))(3). Under fast magic-angle spinning (MAS) conditions (25 kHz), three resonances are clearly resolved and assigned to the three unique crystallographic sites. This assignment is based on the Fermi-contact delocalization interaction between the unpaired...
متن کاملLi+ ionic conductivities and diffusion mechanisms in Li-based imides and lithium amide.
In this study, both experimental ionic conductivity measurements and the first-principles simulations are employed to investigate the Li(+) ionic diffusion properties in lithium-based imides (Li(2)NH, Li(2)Mg(NH)(2) and Li(2)Ca(NH)(2)) and lithium amide (LiNH(2)). The experimental results show that Li(+) ions present superionic conductivity in Li(2)NH (2.54 × 10(-4) S cm(-1)) and moderate ionic...

We investigate in this paper the performance of a simple file sharing principle. For this purpose, we consider a system composed of N peers becoming active at exponential random times; the system is initiated with only one server offering the desired file and the other peers after becoming active try to download it. Once the file has been downloaded by a peer, this one immediately becomes a ser...
متن کاملBis[μ2-1,1-(butane-1,4-diyl)-2,3-dicyclohexylguanidinato]bis[(tetrahydrofuran)lithium](Li—Li)
In the dinuclear centrosymmetric title complex, [Li(2)(C(17)H(30)N(3))(2)(C(4)H(8)O)(2)], the Li(+) cation is coordinated by three N atoms from two guanidinate ligands and an O atom from tetra-hydro-furan (THF) in a strongly distorted tetrahedral environment. In the guanidinate-bridged THF-stabilized dimer the Li⋯Li separation is short at 2.479 (8) Å.
