Dicaesium hexa-mercury hepta-sulfide.

ABSTRACT: The title compound, Cs(2)Hg(6)S(7), crystallizes in a new structure type that is closely related to that of K(2)Zn(6)O(7). The structure comprises a three-dimensional mercury sulfide network that is composed of channels. These channels, which are along [001], are of two different diameters. The crystal structure contains one Cs, two Hg, and three S atoms in the asymmetric unit. The Cs, one Hg, and one S atom are at sites of symmetry m, whereas a second S atom is at a site of symmetry 2mm. The Hg atoms are bound to the S atoms in both three- and four-coordinate geometries. The caesium cations occupy the central spaces of the larger diameter channels and exhibit a coordination number of 7.

Crystal structure of hepta-guanidinium nona-hydrogen bis-[α-hexa-molybdoplatinate(IV)] hepta-hydrate.

Project description:The title compound, (CH6N3)7H9[PtMo6O24]2·7H2O, containing the well-known Anderson-type heteropolyoxomolybdate, was obtained by recrystallization of its powdered guanidinium salt. The protonated O atoms in the polyanion were confirmed by electron-density maps, inter-polyanion hydrogen bonds and bond-valance sums (BVS). The {[H4.5PtMo6O24]2}(7-) polyanion is the same as that already characterized in K7[H4.5PtMo6O24]2·11H2O [space group P-1; Lee & Joo (2010 ▶). Acta Cryst. E66, i8-i9]. The heteropolyanions form inversion-generated dimers, {[H4.5PtMo6O24]2}(7-), held together by each of the four μ3-O-H⋯μ1-O, two μ2-O-H⋯μ2-O hydrogen bonds and one centrosymmetric μ3-O-H-μ3-O hydrogen bond. The H atom of the centrosymmetric hydrogen bond is located on an inversion centre. One guanidinium ion and one water mol-ecule are equally disordered about a twofold rotation axis.

Redetermination of hexa-sodium hepta-molybdate(VI) 14-hydrate.

Project description:The structure of the title compound, Na(6)(Mo(7)O(24))·14H(2)O, has been redetermined [Sjöbom & Hedman (1973). Acta Chem. Scand.27, 3673-3674] and the hydrogen atoms have been located. The Na(+) cations adopt distorted octa-hedral geometries and the structure of the [Mo(7)O(24)](6-) anion is consistent with those of other hepta-molbydates. In the crystal, numerous O-H?O hydrogen bonds help to establish the packing.

Triammonium hexa-hydroxidoocta-deca-oxidohexa-molybdogallate(III) hepta-hydrate.

Project description:The title compound, (NH(4))(3)[GaMo(6)(OH)(6)O(18)]·7H(2)O, contains two centrosymmetric GaMo(6) B-type Anderson cluster units consisting of central GaO(6) octa-hedra surrounded by a hexa-gonal assembly of MoO(6) edge-sharing octa-hedra. Like other B-type Anderson clusters, where the central Mo atom is substituted with a di- or trivalent metal ion, the central six μ(3)-oxido bridges are protonated. The average Ga-O bond length is 1.97 (1) Å, whereas the average Mo-O distances are 2.29 (2), 1.94 (1) and 1.709 (5) Å, respectively, for Mo-(μ(3)-OH), Mo-(μ(2)-O) and Mo=O bonds. In the crystal structure, the Ga(μ(3)-OH)(6)Mo(6)O(18) (3-) polyanionic clusters are surrounded by NH(4) (+) cations and solvent water mol-ecules, forming an extended network of hydrogen bonds.

Nucleation of mercury sulfide by dealkylation.

Project description:Metal sulfide minerals are assumed to form naturally at ambient conditions via reaction of a metallic element with (poly)sulfide ions, usually produced by microbes in oxygen-depleted environments. Recently, the formation of mercury sulfide (β-HgS) directly from linear Hg(II)-thiolate complexes (Hg(SR)2) in natural organic matter and in cysteine solutions was demonstrated under aerated conditions. Here, a detailed description of this non-sulfidic reaction is provided by computations at a high level of molecular-orbital theory. The HgS stoichiometry is obtained through the cleavage of the S-C bond in one thiolate, transfer of the resulting alkyl group (R') to another thiolate, and subsequent elimination of a sulfur atom from the second thiolate as a thioether (RSR'). Repetition of this mechanism leads to the formation of RS-(HgS)n-R chains which may self-assemble in parallel arrays to form cinnabar (α-HgS), or more commonly, quickly condense to four-coordinate metacinnabar (β-HgS). The mechanistic pathway is thermodynamically favorable and its predicted kinetics agrees with experiment. The results provide robust theoretical support for the abiotic natural formation of nanoparticulate HgS under oxic conditions and in the absence of a catalyst, and suggest a new route for the (bio)synthesis of HgS nanoparticles with improved technological properties.

Crystal structure of dicaesium strontium hexa-cyanidoferrate(II), Cs2Sr[Fe(CN)6], from laboratory X-ray powder data.

Project description:Ferrocyanides with general formula A I xB II y [Fe(CN)6], where A and B are cations, are thought to accept many substitutions on the A and B positions. In this communication, the synthesis and crystal structure of Cs2Sr[Fe(CN)6] are reported. The latter was obtained from K2Ba[Fe(CN)6] particles, put in contact with caesium and strontium ions. Hence, a simultaneous ion-exchange mechanism (Cs for K, Sr for Ba) occurs to yield Cs2Sr[Fe(CN)6]. The synthesis protocol shows that K2BaFe(CN)6 particles can be used for the simultaneous trapping of radioactive caesium and strontium nuclides in water streams. Cs2Sr[Fe(CN)6] adopts the cryolite structure type and is isotypic with the known compound Cs2Na[Mn(CN)6] [dicaesium sodium hexa-cyanidomanganate(III)]. The octa-hedrally coordinated Sr and Fe sites both are located on inversion centres, and the eightfold-coordinated Cs site on a general position.

Redetermination of hepta-potassium nona-hydrogen bis-[?-hexa-molybdoplatinate(IV)] undeca-hydrate.

Project description:Previously reported at a temperature of 298?(2)?K [Lee & Joo (2007 ?). Acta Cryst. E63, i11-i13], the title compound, K(7)[H(9)?-Pt(2)Mo(12)O(48)]·11H(2)O or K(7)[H(4.5)?-PtMo(6)O(24)](2)·11H(2)O, was redetermined at 146?(2)?K in order to determine whether the H atom in the hydrogen bond that crosses the center of symmetry was located at the center of symmetry or disordered around it as assumed in the previous study. During the present low-temperature study it was found on the center of symmetry. One water molecule shows half-occupancy.

Microbial- and thiosulfate-mediated dissolution of mercury sulfide minerals and transformation to gaseous mercury.

Project description:Mercury (Hg) is a toxic heavy metal that poses significant environmental and human health risks. Soils and sediments, where Hg can exist as the Hg sulfide mineral metacinnabar (β-HgS), represent major Hg reservoirs in aquatic environments. Metacinnabar has historically been considered a sink for Hg in all but severely acidic environments, and thus disregarded as a potential source of Hg back to aqueous or gaseous pools. Here, we conducted a combination of field and laboratory incubations to identify the potential for metacinnabar as a source of dissolved Hg within near neutral pH environments and the underpinning (a)biotic mechanisms at play. We show that the abundant and widespread sulfur-oxidizing bacteria of the genus Thiobacillus extensively colonized metacinnabar chips incubated within aerobic, near neutral pH creek sediments. Laboratory incubations of axenic Thiobacillus thioparus cultures led to the release of metacinnabar-hosted Hg(II) and subsequent volatilization to Hg(0). This dissolution and volatilization was greatly enhanced in the presence of thiosulfate, which served a dual role by enhancing HgS dissolution through Hg complexation and providing an additional metabolic substrate for Thiobacillus. These findings reveal a new coupled abiotic-biotic pathway for the transformation of metacinnabar-bound Hg(II) to Hg(0), while expanding the sulfide substrates available for neutrophilic chemosynthetic bacteria to Hg-laden sulfides. They also point to mineral-hosted Hg as an underappreciated source of gaseous elemental Hg to the environment.

syn,syn-15,17-Di-2-naphthyl-hexa-cyclo-[10.2.1.1.1.0.0]hepta-decane deuterochloro-form monosolvate.

Project description:The main molecule of the title compound, C(37)H(36)·CDCl(3), is a hydro-carbon with two naphthalene segments attached to opposite ends of a rigid norbornylogous spacer with an overall structure that is approximately C-shaped. The dihedral angle between the naphthalene ring planes is 9.27?(7)°. The cleft that exists between the naphthalene rings is large enough that the compound crystallizes with a solvent mol-ecule (CDCl(3)) in the cleft. The CDCl(3) solvent mol-ecule is present in two disordered orientations in a 3:2 ratio, each involving C-D?? to C(6) ring centers.
