The asymmetric unit of the title compound, (C(8)H(10)NO(2))(4)[SnCl(6)]Cl(2), contains two (4-meth-oxy-carbon-yl)anilinium cations, one chloride anion and one half of a hexa-chlorido-stannate(IV) dianion situated on a twofold rotation axis. All aminium H atoms are involved in N-H⋯Cl hydrogen bonding, which consolidate the crystal packing along with weak C-H⋯O inter-actions.
In the title compound, [N(C4H9)4][Sn(C4H9)Cl4], the Sn(IV) atom of the stannate anion has a trigonal-bipyramidal coordination sphere by two Cl atoms and one butyl chain in the equatorial plane and by two Cl atoms in the apical positions. Two of the four butyl chains of the tetra-butyl-ammonium cation are partially disordered, each with refined site occupancies of 0.691 (6):0.309 (6). Weak C-H⋯C...
In the title compound, (C(7)H(11)N(2))(2)[SnBr(4)(C(7)H(7))(2)], the tetra-bromidobis(4-methyl-phen-yl)stannate(IV) anion possesses a centre of inversion located at the Sn(IV) atom. In the crystal structure, two inversion-related cations are linked to the anion via weak N-H⋯Br hydrogen bonds.
Optical waveguide lightmode spectroscopy (OWLS) is usually applied as a biosensor system to the sorption-desorption of proteins to waveguide surfaces. Here, we show that OWLS can be used to monitor the quality of oxide thin film materials and of coatings of pulsed laser deposition synthesized CdSe quantum dots (QDs) intended for solar energy applications. In addition to changes in data treatmen...
The subsolidus phase relationships in the ZnO–InO1.5–SnO2 system were investigated at 12751C using X-ray diffraction. Each of the end members of the ternary diagram is a transparent conducting oxide. There are two substantial solid solutions in the ternary phase space, the bixbyite solid solution In2 2xZnxSnxO3 (x5 0–0.40), and the indium substituted zinc stannate spinel, Zn(2 x)Sn(1 x)In2xO4 (...
The tin atom in the substituted ammonium stannate(IV), (C(5)H(6)N)(2)[SnBr(3)(C(6)H(4)Cl)(2)Cl], lies on a center of symmetry in a distorted octa-hedral coordination geometry. Each independent halogen site is occupied by bromine and chlorine anions in an approximate 3:1 ratio. The pyridinium cation forms a hydrogen bond to only one of the halogen atoms.
Nanocrystalline perovskite-type BaSnO3 was obtained via microwave-assisted hydrothermal route followed by annealing at variable temperature. The samples composition and microstructure were characterized. Particle size of 18–23 nm was unaffected by heat treatment at 275–700 ̋C. Materials DC-conduction was measured at variable temperature and oxygen concentration. Barium stannate exhibited n-type...
Between 1924 and 1947, Gino Severini decorated five churches in the Romand region of Switzerland with monumental religious wall paintings. This mural art played an important role Italian artist's career despite being mostly unknown not easily found. The painting methods materials these modern Swiss murals were characterized by combining historical archival research onsite visual scientific exam...
