| Popis: | A novel tin(II)-compound, bis(η 2 -N,O-2-[4,5-dimethyloxazolyl]-1,1,1-trifluoro-propen-2-olato)tin, Sn II [(Me 2 C 3 NO)(CHCOCF 3 )] 2 ( 1 ), was obtained by reacting Sn[N(SiMe 3 ) 2 ] 2 with 2 M equivalents of the β-heteroarylalkenol, (Me 2 C 3 NO)(CHCOHCF 3 ) ( 2 ). The molecular structures of ligand and the tin derivative were elucidated by single crystal X-ray diffraction and multi-nuclear NMR spectroscopic studies, which confirmed the monomeric nature and fourfold coordination of the tin(II) center with a pseudo-pyramidal geometry. The bidentate chelating mode of 2 imparted intriguingly high air stability to 1 , which together with its high volatility make it an interesting precursor for the chemical vapor deposition (CVD) process. CVD of 1 on gold-coated Al 2 O 3 substrates produced single crystalline SnO 2 nanowires by vapor–liquid–solid growth mechanism. Transmission electron microscopy studies and X-ray diffraction data confirmed the high crystallinity of SnO 2 nanowires possessing an average diameter of 90 nm. |
