The five-coordinate Sn atom in the title mixed organyl stannate compound, (C(12)H(24)N)[Sn(C(5)H(9))(C(6)H(5))(2)(C(2)ClF(2)O(2))], is in a trans-C(3)SnO(2) trigonal-bipyramidal coordination environment. The NH(2) groups of the cations act as hydrogen-bond donors to two symmetry-related anions, resulting in the formation of linear chains. One of the phenyl rings is disordered over two sites wit...

In the title mixed-organyl stannate, (C(12)H(24)N)[Sn(C(6)H(5))(2)(C(6)H(11))(CClF(2)O(2))(2)], there are two cations and two anions in the asymmetric unit. Each five-coordinate Sn atom shows trans-C(3)SnO(2) trigonal bipyramidal coordination. The four Sn-O distances are approximately equal in the two independent anions. Each ammonium cation serves as a hydrogen-bond donor to two stannates, the...

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.

The asymmetric unit of the title organotin salt, (C(8)H(20)N)[Sn(C(6)H(5))(3)(CH(4)O(3)P)(2)], contains two dibutyl-ammonium cations and two stannate(IV) anions consisting each of two monodentately bonding methyl hydrogenphosphate groups attached to an Sn(C(6)H(5)) unit. The overall coordination environment of the two Sn(IV) atoms is trigonal-bipyramidal defined by three phenyl C atoms in equat...

Wide-bandgap perovskite stannates are of interest for the emergent all-oxide transparent electronic devices due to their unparalleled room temperature electron mobility. Considering advantage amorphous material in integrating with non-semiconductor platforms, we herein reported optical and properties prototypical stannate, barium stannate (BaSnO3) thin films, which were deposited at annealed va...

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...
