RbSn(2)(PO(4))(3), a NASICON-type phosphate.

ABSTRACT: The title compound, rubidium ditin(IV) tris-(phosphate), RbSn(2)(PO(4))(3), belongs to the NASICON-type family of phosphates and crystallizes in the space group R[Formula: see text]. The structure is composed of PO(4) tetra-hedra (1 symmetry) and two slightly distorted SnO(6) octa-hedra, both with 3. symmetry, which are inter-linked through corner-sharing O atoms to form a (3) (?)[Sn(2)(PO(4))(3)](-) framework. The Rb(+) cations are located on threefold inversion axes in the voids of this framework and exhibit a coordination number of 12. The crystal studied was twinned by merohedry with a component ratio of 0.503:0.497.

Na(4)FeFe(PO(4))(3), a new synthetic NASICON-type phosphate.

Project description:This paper reports the crystal structure of tetra-sodium diiron tris(phosphate), Na(4)Fe(2+)Fe(3+)(PO(4))(3), which has been synthesized hydro-thermally at 773 K and 0.1 GPa. The crystal structure has been refined in the space group Rc and is identical to that of γ-NASICON. The heteropolyhedral framework is based on a regular alternation, in three dimensions, of corner-sharing PO(4) tetra-hedra and FeO(6) octa-hedra, constituting so-called 'lantern units' stacked along the c axis. The Na(+) cations are distributed over two crystallographic sites: the six-coordinated Na1 site which lies between two 'lantern units', and the eight-coordinated Na2 site which lies at the same z value as the P site.

NASICON-related Na?.?Mn?.?Fe?.?(PO?)?.

Project description:The solid solution, sodium [iron(III)/manganese(II)] tris-(orthophosphate), Na?.?Mn?.?Fe?.?(PO?)?, was obtained using a flux method. Its crystal structure is related to that of NASICON-type compounds. The [(Mn/Fe)?(PO?)?] framework is built up from an (Mn/Fe)O?octa-hedron (site symmetry 3.), with a mixed Mn/Fe occupancy, and a PO? tetra-hedron (site symmetry .2). The Na? cations are distributed over two partially occupied sites in the cavities of the framework. One Na? cation (site symmetry -3.) is surrounded by six O atoms, whereas the other Na? cation (site symmetry .2) is surrounded by eight O atoms.

NASICON-type Na(3)V(2)(PO(4))(3).

Project description:Single crystals of the title compound, tris-odium divanadium(III) tris-(orthophosphate), were grown from a self-flux in the system Na(4)P(2)O(7)-NaVP(2)O(7). Na(3)V(2)(PO(4))(3) belongs to the family of NASICON-related structures and is built up from isolated [VO(6)] octa-hedra (3. symmetry) and [PO(4)] tetra-hedra (.2 symmetry) inter-linked via corners to establish the framework anion [V(2)(PO(4))(3)](3-). The two independent Na(+) cations are partially occupied [site-occupancy factors = 0.805?(18) and 0.731?(7)] and are located in channels with two different oxygen environments, viz sixfold coordination for the first (. symmetry) and eightfold for the second (.2 symmetry) Na(+) cation.

A new langbeinite-type phosphate: K(2)AlSn(PO(4))(3).

Project description:Single crystals of the title compound, dipotassium aluminium tin(IV) tris-[phosphate(V)], K(2)AlSn(PO(4))(3), were synthesized by a high temperature reaction in a platinum crucible. In the structure, the Al(III) and Sn(IV) atoms occupy the same site on a threefold rotation axis with occupational disorder in a 1:1 ratio. In the three-dimensional structure, Al/SnO(6) octa-hedra and PO(4) tetra-hedra are inter-connected via their vertices, yielding a [Al/SnP(3)O(12)](n) framework. The K atoms (site symmetry 3) reside in the large cavities delimited by the [Al/SnP(3)O(12)](n) framework, and are surrounded by 12 O atoms.

NASICON-Structured NaTi2(PO4)3 for Sustainable Energy Storage.

Project description:Several emerging energy storage technologies and systems have been demonstrated that feature low cost, high rate capability, and durability for potential use in large-scale grid and high-power applications. Owing to its outstanding ion conductivity, ultrafast Na-ion insertion kinetics, excellent structural stability, and large theoretical capacity, the sodium superionic conductor (NASICON)-structured insertion material NaTi2(PO4)3 (NTP) has attracted considerable attention as the optimal electrode material for sodium-ion batteries (SIBs) and Na-ion hybrid capacitors (NHCs). On the basis of recent studies, NaTi2(PO4)3 has raised the rate capabilities, cycling stability, and mass loading of rechargeable SIBs and NHCs to commercially acceptable levels. In this comprehensive review, starting with the structures and electrochemical properties of NTP, we present recent progress in the application of NTP to SIBs, including non-aqueous batteries, aqueous batteries, aqueous batteries with desalination, and sodium-ion hybrid capacitors. After a thorough discussion of the unique NASICON structure of NTP, various strategies for improving the performance of NTP electrode have been presented and summarized in detail. Further, the major challenges and perspectives regarding the prospects for the use of NTP-based electrodes in energy storage systems have also been summarized to offer a guideline for further improving the performance of NTP-based electrodes.

The iron phosphate CaFe(3)(PO(4))(3)O.

Project description:A new iron phosphate, calcium triiron(III) tris-(phosphate) oxide, CaFe(3)(PO(4))(3)O, has been isolated and shown to exhibit a three-dimensional structure built by FeO(6) octa-hedra, FeO(5) trigonal bipyramids and PO(4) tetra-hedra. The FeO(x) (x = 5, 6) polyhedra are linked through common corners and edges, forming [Fe(6)O(28)](?) chains with branches running along [010]. Adjacent chains are connected by the phosphate groups via common corners and edges, giving rise to a three-dimensional framework analogous to those of the previously reported SrFe(3)(PO(4))(3)O and Bi(0.4)Fe(3)(PO(4))(3)O structures, in which the Ca(2+) cations occupy a single symmetry non-equivalent cavity.

The iron phosphate NaBaFe(2)(PO(4))(3).

Project description:A new iron phosphate, sodium barium diiron tris-(phosphate), NaBaFe(2)(PO(4))(3), has been synthesized by the flux method and shown to exhibit the well known langbeinite type structure. The Na, Ba and Fe atoms all lie on threefold axes, while the P and O atoms occupy general positions, one of the O atoms being disordered over two positions, with site occupancy factors of ca 0.7 and 0.3. The [Fe(2)(PO(4))(3)](?) framework consists of FeO(6) octa-hedra sharing all their corners with the PO(4) tetra-hedra. The Na(+) and Ba(2+) cations are almost equally distributed over two distinct cavities, in which they occupy slightly different positions.

The ?-modification of trizinc borate phosphate, Zn(3)(BO(3))(PO(4)).

Project description:Crystals of ?-Zn(3)(BO(3))(PO(4)) have been grown by the Kyropoulos method. The asymmetric unit contains three Zn sites, three B-atom sites (all with symmetry 3), two P sites (both with m symmetry) and nine O-atom sites (four with m symmetry). The fundamental building units of the title structure are isolated BO(3) triangles and PO(4) tetra-hedra, which are bridged by ZnO(4) tetra-hedra or ZnO(5) trigonal bipyramids through common O atoms, leading to a three-dimensional framework structure. Some significant structural differences between the ?-polymorph and the ?-polymorph are discussed.

Heptamagnesium bis-(phosphate) tetra-kis-(hydrogen phosphate) with strong hydrogen bonds: Mg(7)(PO(4))(2)(HPO(4))(4).

Project description:The title compound, Mg(7)(PO(4))(2)(HPO(4))(4), was synthesized by the hydro-thermal method. The structure is based on a framework of edge- and corner-sharing MgO(6) and MgO(4)(OH)(2) octa-hedra, an MgO(5) polyhedron, PO(4) and PO(3)(OH) tetra-hedra. All atoms are in general positions except for one Mg atom, which is located on a crystallographic inversion centre. The OH groups, bridging Mg-(OH)-P, are involved in strong hydrogen bonds. Compounds with the general formula M(7)(PO(4))(2)(HPO(4))(4) (M = Mg, Mn, Fe and Co) are all isostructural with their homologue arsenate Mg(7)(AsO(4))(2)(HAsO(4))(4).

Sodium samarium tetra-kis-(poly-phosphate), NaSm(PO(3))(4).

Project description:NaSm(PO(3))(4) has been prepared by solid state reactions. It belongs to type II of the structural family of M(I)Ln(III)(PO(3))(4) compounds (M(I) = alkali metal and Ln(III) = rare earth metal) and is composed of (?)(PO(3))(n)](n-) polyphosphate chains with a repeating unit of four PO(4) tetra-hedra. The chains extend parallel to [100] and share O atoms with irregular SmO(8) polyhedra, forming a three-dimensional framework which delimits tunnels occupied by Na(+) cations in a distorted octa-hedral environment.
