BaCo(2)(AsO(4))(2).

ABSTRACT: Suitable single crystals of the title compound, barium dicobalt(II) bis-[orthoarsenate(V)], were prepared under hydro-thermal conditions. This phase belongs to a series of compounds with general formula AM(2)(XO(4))(2), where A = alkaline earth metal, M = Mg or a divalent first-row transition element, and X = P, As or V. BaCo(2)(AsO(4))(2) is isotypic with BaNi(2)(XO(4))(2) (X = P, V or As) and is characterized by brucite-like sheets of edge-sharing CoO(6) octa-hedra (3 symmetry) parallel to (001), with one-third of the octa-hedral positions being vacant. The sheets are capped above and below by AsO(4) tetra-hedra (3 symmetry) and are inter-connected by distorted BaO(12) cubocta-hedra ( symmetry).

La variete ?-NaMoO(2)(AsO(4)).

Project description:The title compound, sodium dioxidomolybdenum(VI) arsenate(V), ?-NaMoO(2)AsO(4), was prepared by solid-state reaction at 953?K. In the crystal structure, the AsO(4) tetra-hedra and MoO(6) octa-hedra (both with m symmetry) share corner atoms to form a three-dimensional framework that delimits cavities parallel to [010] where disordered six-coordinated sodium cations (half-occupation) are located. Structural relationships between the different orthoarsenates of the AMoO(2)AsO(4) series (A = Ag, Li, Na, K and Rb) are discussed.

Redetermination of conichalcite, CaCu(AsO(4))(OH).

Project description:The crystal structure of conichalcite [calcium copper(II) arsenate(V) hydroxide], with ideal formula CaCu(AsO(4))(OH), was redetermined from a natural twinned specimen found in the Maria Catalina mine (Chile). In contrast to the previous refinement from photographic data [Qurashi & Barnes (1963 ?). Can. Mineral. 7, 561-577], all atoms were refined with anisotropic displacement parameters and with the H atom located. Conichalcite belongs to the adelite mineral group. The Jahn-Teller-distorted [CuO(6)] octa-hedra share edges, forming chains running parallel to [010]. These chains are cross-linked by eight-coordinate Ca atoms and by sharing vertices with isolated AsO(4) tetra-hedra. Of five calcium arsenate minerals in the adelite group, the [MO(6)] (M = Cu, Zn, Co, Ni and Mg) octa-hedron in conichalcite is the most distorted, and the donor-acceptor O-H?O distance is the shortest.

A sodium calcium arsenate, NaCa(AsO(4)).

Project description:The title compound, NaCa(AsO(4)), was synthesized using a hydro-thermal method at 633-643?K. It has a dense structure composed of alternating layers of distorted [CaO(6)] octa-hedra and layers of [AsO(4)] tetra-hedra and distorted [NaO(6)] octa-hedra, stacked along the a axis. The As, Ca and two O atoms lie on the mirror plane at y = 1/4 (i.e. 4c), while the Na atom lies on an inversion centre (1/2, 1/2, 0) (i.e. 4b). Each distorted [CaO(6)] octa-hedron shares four equatorial common O vertices with four neighboring octa-hedra, forming a layer parallel to (100), whereas each distorted [NaO(6)] octa-hedron shares two opposite edges with two neighboring ones, forming a chain running along [010]. Each isolated [AsO(4)] tetra-hedron shares two edges with two different [NaO(6)] octa-hedra in one [NaO(6)] chain and a vertex with another chain. Simultaneously the above [AsO(4)] tetra-hedron located in a four-membered [CaO(6)] ring shares one edge of its base facet with one [CaO(6)] octa-hedron and three corners with three other [CaO(6)] octa-hedra of one [CaO(6)] layer, and the remaining apex is shared with another [CaO(6)] layer. [NaO(6)] octa-hedra and [CaO(6)] octa-hedra are linked to each other by sharing edges and vertices.

NaAg(2)Mo(3)O(9)AsO(4).

Project description:The title compound, sodium disilver arsenatotrimolybdate, Na(0.93?(1))Ag(2.07?(1))Mo(3)AsO(13), was prepared by a solid-state reaction. In the crystal structure, isolated AsO(4) tetra-hedra share corners with groups of three edge-sharing MoO(6) octa-hedra. This arrangement leads to the formation of anionic (1) (?)[Mo(3)AsO(13)](n) ribbons extending parallel to [100]. The three metal sites show occupational disorder by Ag(I) and Na(I) cations, each with a different Ag:Na ratio. The metal cations are situated in the space between the ribbons and are surrounded by terminal O atoms of the ribbons in the form of distorted MO(7) polyhedra (M = Ag, Na) for distances < 3.0?Å. The title compound shows weak ionic conductivity. Structural relationships between different compounds in the quaternary systems M-Sb-P-O, M-Nb-P-O and M-Mo-As-O (M is Ag or an alkali metal) are also discussed.

The alluaudite-like arsenate NaCaMg(3)(AsO(4))(3).

Project description:The title compound, sodium calcium trimagnesium tris-(arsenate), an alluaudite-like arsenate, was prepared by solid-state reaction at high temperature. The structure is built up from edge-sharing MgO(6) octa-hedra in chains associated with the AsO(4) arsenate groups. The three-dimensional network leads to two different tunnels occupied statistically by Na(+) and Ca(2+). One As and one Mg atom lie on twofold rotation axes; one Na and one Ca are disordered over two sites with occupancies of 0.7 and 0.3 and these sites lie on a twofold rotation axis and an inversion centre, respectively.

Wyllieite-type Ag(1.09)Mn(3.46)(AsO(4))(3).

Project description:Single crystals of wyllieite-type silver(I) manganese(II) tris-orthoarsenate(V), Ag(1.09)Mn(3.46)(AsO(4))(3), were grown by a solid-state reaction. The three-dimensional framework is made up from four Mn(2+)/Mn(3+) cations surrounded octa-hedrally by O atoms. The MnO(6) octa-hedra are linked through edge- and corner-sharing. Three independent AsO(4) tetra-hedra are linked to the framework through common corners, delimiting channels along [100] in which two partly occupied Ag(+) sites reside, one on an inversion centre and with an occupancy of 0.631?(4), the other on a general site and with an occupancy of 0.774?(3), both within distorted tetra-hedral environments. One of the Mn sites is also located on an inversion centre and is partly occupied, with an occupancy of 0.916?(5). Related compounds with alluaudite-type or rosemaryite-type structures are compared and discussed.

Episodic transport of discrete magma batches beneath Aso volcano.

Project description:Magma ascent, storage, and discharge in the trans-crustal magmatic system are keys to long-term volcanic output and short-term eruption dynamics. How a distinct magma batch transports from a deep reservoir(s) to a pre-eruptive storage pool with eruptible magma remains elusive. Here we show that repetitive very-long-period signals (VLPs) beneath the Aso volcano are preceded by a short-lived (~50-100 s), synchronous deformation event ~3 km apart from the VLP source. Source mechanism of a major volumetric component (~50-440 m3 per event) and a minor low-angle normal-fault component, together with petrological evidence, suggests episodic transport of discrete magma batches from an over-pressured chamber roof to a pre-eruptive storage pool near the brittle-ductile transition regime. Magma ascent velocity, decompression rate, and cumulative magma output deduced from recurrent deformation events before recent 2014 and 2016 eruptions reconcile retrospective observations of the eruption style, tephra fallouts, and plume heights, promising real-time evaluation of upcoming eruptions.
