In the reaction of 8-hy-droxy-quinoline, 2-methyl-8-hy-droxy-quinoline and stannic chloride, the 2-methyl-8-hy-droxy-quinoline is protonated, yielding the disolvated title salt, (C(10)H(10)NO)[SnCl(4)(C(9)H(6)NO)]·2CH(3)OH. The Sn(IV) atom in the anion is N,O-chelated by the hy-droxy-quinolinate in a cis-SnNOCl(4) octa-hedral geometry. In the crystal, the cation, anion and solvent mol-ecules ar...

In present study spray pyrolysis technique was employed to prepare pure and doped CdSnO3 thin films. The spray pyrolyzed thin films were observed to be nanostructured in nature with particle size less than 10 nm and characterized to investigate its structural, microstructural and chemical properties by means of XRD, SEM/EDS, TEM and surface profilometry. Pure and Zn doped CdSnO3 nanostructured ...

The Sn atom in the title salt, (C(7)H(11)N(2))(2)[SnBr(4.67)Cl(1.33)], lies on a center of symmetry within an octa-hedron of disordered halogen atoms. The three independent halogen atoms are each a mixture of bromine and chlorine atoms [with site occupancies for bromine of 0.614 (1), 0.831 (1) and 0.888 (1)]. An N-H⋯ hydrogen bond is present.

In the disolvated title salt, (C(13)H(10)NO)[SnCl(4)(C(10)H(8)NO)]·2CH(3)OH, the Sn(IV) atom is chelated by the N,O-bidentate 2-methyl-quinolin-8-olate ion and is further coordinated by four chloride ions, showing a distorted octa-hedral SnNOCl(4) geometry. In the crystal, the cation and anion are linked to the methanol mol-ecules by O-H⋯O and N-H⋯O hydrogen bonds.

Abstract Protonic ceramic fuel cells (PCFCs) offer a convenient means for electrochemical conversion of chemical energy into electricity at intermediate temperatures with very high efficiency. Although BaCeO 3 - and BaZrO -based complex oxides have been positioned as the most promising PCFC electrolytes, design new protonic conductors improved properties is paramount importance. Within present ...
