Inorganic semiconductor ferroelectrics such as BiFeO3 have shown great potential in photovoltaic and other applications. Currently, semiconducting properties and the corresponding application in optoelectronic devices of hybrid organo-plumbate or stannate are a hot topic of academic research; more and more of such hybrids have been synthesized. Structurally, these hybrids are suitable for explo...

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.

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...
