用元素分析、核磁共振谱和热重分析对乙黄原酸镉（11）的双-3-甲基吡啶和双-4-甲基吡啶配合物进行了表征。两个甲基吡啶衍生物的单晶X-射线结构也已被确定，并显示显示顺式，顺式，顺式构型的N-和S-供体配体。该化合物已被用作单一源前体，通过气溶胶辅助化学气相沉积在220和350 ℃下在二氧化硅涂覆的玻璃基板上沉积存款CdS膜。用扫描电子显微镜分析了薄膜的表面形貌，用粉末X射线衍射研究了薄膜的晶相。从3-甲基吡啶加合物沉积的膜包括更密集的包装和更高度结晶的六方CdS比由其他两种前体中的任何一种所提供的。发现微晶尺寸为
Bis-3-methylpyridine and bis-4-methylpyridine complexes of cadmium(11) ethylxanthate have been characterized by elemental analysis, NMR spectroscopy, and thermogravimetric analysis. The single crystal X-ray structures of both methylpyridine derivatives have also been determined and shown to display a cis, cis, cis-configuration of the N- and S-donor ligands. The compounds have been utilized as single source precursors to deposit CdS films on silica-coated glass substrates at 220 and 350 degrees C by aerosol-assisted chemical vapor deposition. The surface morphology of the films has been examined by scanning electron microscopy analysis and the crystalline phases were studied by powder X-ray diffraction. The films deposited from the 3-methylpyridine adduct comprised more densely packed and more highly crystalline hexagonal CdS than those provided by either of the other two precursors. The crystallite sizes were found to be
