以黄原酸铁（III）单源前驱体[Fe（S2 COR）3]（R =甲基、乙基、异丙基和1-丙基）为原料，采用两种简单、高效、低成本的方法（旋涂法和固相沉积法）存款了硫化铁薄膜和纳米结构。测定了正丙基黄原酸铁和异丙基黄原酸铁的单晶X-射线结构。配合物的热重分析（TGA）研究表明，配合物的分解产生硫化铁，黄铁矿或亚硫酸铁。利用X射线衍射仪（XRD）研究了硫化铁薄膜和粉末样品的结晶度，并利用扫描电子显微镜（SEM）研究了其形貌。采用黄原酸铁单源前驱体，通过旋涂和固相沉积方法制备了硫化铁薄膜和纳米结构存款。
Iron(iii) xanthate single-source precursors [Fe(S2COR)3] (R = methyl, ethyl, isopropyl and 1-propyl) were used to deposit iron sulfide thin films and nanostructures by two simple, efficient and low-cost methods (spin coating and solid state deposition). The single-crystal X-ray structures of the iron(iii) n-propyl xanthate and iron(iii) iso-propyl xanthate have been determined. Thermogravimetric analysis (TGA) studies of the complexes shows that decomposition of the complexes produces iron sulfide, pyrite or trolite. The crystallinity of iron sulfide thin films and powder samples was studied using X-ray diffraction (XRD), and their morphology was studied by scanning electron microscopy (SEM). Iron(iii) xanthate single-source precursors were used to deposit iron sulfide thin films and nanostructures by spin coating and solid state deposition.
