The Sn(IV) atom of the stannate anion in the title salt, (C(7)H(11)N(2))(2)[SnBr(4)(C(6)H(5))(2)], lies on a center of inversion in a tetra-gonally compressed octa-hedron. The two independent Br atoms in the anion are hydrogen-bond acceptors for the same cation.

We report density functional studies of electron rich interfaces between KTaO3 or KNbO3 and CaSnO3 or ZnSnO3 and in particular the nature of the interfacial electron gasses that can be formed. We find that depending on the details these may occur on either the transition metal or stannate sides of the interface and in the later case can be shifted away from the interface by ferroelectricity. We...

The cation and the anion in the title salt, (C(6)H(16)N)[SnCl(4)(C(6)H(4)NO(2))], are linked by an N-H⋯O hydrogen bond. The Sn(IV) atom in the stannate anion is chelated by the pyridine-2-carboxyl-ate group and exists in a cis-SnCl(4)NO octa-hedral geometry. The cation is disordered over two positions in a 0.564 (1):0.436 (1) ratio.

This work presents first-principles calculations on the surface and defect impact upon zinc stannate (ZS) materials with perovskite bulk structures. The structure electronic properties of both a perfect 001 surfaces point ZS were investigated by means density functional theory calculations. cohesive energies those O, Sn, or Zn defects decreased compared that ZS. Oxygen formed more easily than o...

the nanopowders of sno2, casno3 and ca2sno4 in the size rang of 5-70 nm have been prepared using solid-state reaction technique. the technique is convenient and inexpensive in comparison to the conventional routes of compound prepared and processing where, many steps of mixing and annealing are involved. formation of resultant compounds was explained on the basis of reaction taken place between...

The Sn(IV) atom in the title ammonium stannate, (Et(3)NH)[Sn(C(5)H(3)N(2)O(2))Cl(4)], is chelated by an pyrazine-2-carboxyl-ate ligand and exists in a cis-SnCl(4)NO octa-hedral geometry. The cation and the anion are linked by an N-H⋯N hydrogen bond.
