Tetra-amminelithium triamminelithium tris-ulfide, [Li(NH(3))(4)][Li(NH(3))(3)S(3)].

ABSTRACT: The title compound, [Li(NH(3))(4)](+)[Li(NH(3))(3)S(3)](-), an ammo-niate of the previously unknown lithium tris-ulfide, was obtained from the reaction of lithium and sulfur in liquid ammonia. The asymmetric unit consists of two crystallographically independent formula units. The [Li(NH(3))(4)](+) cations are close to regular LiN(4) tetra-hedra. The anions contain LiSN(3) tetra-hedra; the S-S-S bond angles are 110.43?(5) and 109.53?(5)°. In the crystal, the components are linked by multiple N-H?S hydrogen bonds. A weak N-H?N hydrogen bond is also present.

Tetra-yttrium(III) tris-ulfide disilicate.

Project description:Tetra-yttrium(III) tris-ulfide disilicate, Y(4)S(3)(Si(2)O(7)), crystallizes in the Sm(4)S(3)(Si(2)O(7)) structure type.

Project description:In the tetra-hydro-furan solvate of the title salt, C12H36N6P3 (+)·C24H20B(-)·C4H8O, the cation features short P-P bond lengths [2.1111?(11) and 2.1364?(10)?Å] and a distinctly bent P-P-P angle [104.67?(4)°] that confirm that the mol-ecule is not allene-like. In the crystal, the solvent mol-ecule is linked to the cation via a weak C-H?O hydrogen bond.

Rapid Microwave Synthesis, Characterization and Reactivity of Lithium Nitride Hydride, Li?NH.

Project description:Lithium nitride hydride, Li?NH, was synthesised from lithium nitride and lithium hydride over minute timescales, using microwave synthesis methods in the solid state for the first time. The structure of the microwave-synthesised powders was confirmed by powder X-ray diffraction [tetragonal space group I4?/a; a = 4.8864(1) Å, c = 9.9183(2) Å] and the nitride hydride reacts with moist air under ambient conditions to produce lithium hydroxide and subsequently lithium carbonate. Li?NH undergoes no dehydrogenation or decomposition [under Ar(g)] below 773 K. A tetragonal-cubic phase transition, however, occurs for the compound at ca. 770 K. The new high temperature (HT) phase adopts an anti-fluorite structure (space group Fm 3? m; a = 4.9462(3) Å) with N3- and H- ions disordered on the 4a sites. Thermal treatment of Li?NH under nitrogen yields a stoichiometric mixture of lithium nitride and lithium imide (Li?N and Li?NH respectively).

Project description:The structure of the title compound, NH(4)(C(8)H(20)N)(3)[Mo(8)O(26)], is built up by discrete cations and anions, with two formula units in the asymmetric unit.
