A series of palladium(II) dithiocarbamate complexes [Pd(S2CNRR′)2]·n(py) [where py = pyridine; RR′ = Bz, n = 1 (1); Cy, n = 1 (2); nHex, n = 0 (3) and MeCy, n = 0 (4)] have been synthesized and characterized using various physicochemical techniques and their single crystal structures have been established. The decomposition modes and potential of the complexes as single source precursors (SSPs) for
一系列钯(II)二硫代氨基甲酸酯配合物[Pd(S 2 CNRR')2 ]· n(py)[其中py =吡啶;RR'= Bz,n = 1(1); Cy,n = 1(2);n十六进制,n = 0(3)和MeCy,n = 0(4)]已经使用各种物理化学技术合成和表征,并且已经建立了它们的单晶结构。通过热重分析和衍生热重分析(TGA / DTG)分析了复合物作为单一来源前驱物(SSP)的发展模式和潜力,用于开发硫化钯(PdS)薄膜。通过气溶胶辅助化学气相沉积(AACVD)技术在400、450和500°C的FTO导电玻璃基板上沉积PdS薄膜,并通过X射线衍射(XRD),扫描电子显微镜(SEM),能量表征分散型X射线分析(EDX)表明,该沉积物具有用1四方结构:钯之比为1 :S. PdS微晶的形状和大小以及薄膜的质感取决于沉积温度和所使用的前驱体类型。根据在450°C下由前体(2)制成的PdS膜的紫外-可见光谱,估计出1
