Methylation is an important transformation process for elements in the environment. Herein, headspace solid phase micro-extraction (HP-SPME) coupled with gas chromatography–flame photometric detection (GC-FPD) or gas chromatography–mass spectrometry (GC–MS) techniques were employed to study the photochemical methylation of inorganic tin(II) by eight organic compounds (including acetone, pyruvic...

Reaction of R2SnCl2 (R = Me, nBu, Ph) and the potassium salts of salenN3H3 (N,N0-bis(salicylidene)diethylenetriamine) and saleanN3H5 (N,N0-bis(o-hydroxybenzyl)diethylenetriamine) provided diorganotin(IV) complexes of the composition [Me2Sn(salenN3H)] solvate (solvate = 2.5H2O, MeOH or DMSO), [nBu2Sn(salenN3H)] H2O, [Ph2Sn(salenN3H)] 2EtOH and [Me2Sn(saleanN3H3)] 2.5H2O. In all compounds the tin...

This report is to address the question if black γ-polymorph of cesium tin tri-iodide (B-γ-CsSnI3) can be used as a solid-state hole-transport material in the conventional DSSCs with the N719 dye to replace the liquid electrolyte as reported by I. Chung et al. on Nature 485, 486, (2012). Here we demonstrate rigorously that B-γ-CsSnI3 is not energetically possible to collect photogenerated holes ...

The effect of precursors on the characteristics of tin oxide obtained by chemical vapor deposition (CVD) method was investigated. The synthesis of nanosized tin(IV) oxide was carried out with the use of two different precursors: tin(II) oxalate obtained using tin chloride(II) and oxalic acid; tin(II) oxalate obtained using tin chloride(II); and ammonium oxalate. The synthesized tin(IV) oxide sa...
