  Synthesis of PbSe nanocrystallites using a single-source method. The X-ray crystal structure of lead (II) diethyldiselenocarbamate

  摘要：

  The compounds Pb{Se2CN(C2H5)(2)}(2) and Pb{Se2CN(CH3)(C6H13)}(2) were synthesised and characterised. The X-ray crystal structure of Pb{Se2CN(C2H5)(2)}(2) is reported. The use of these compounds as single-molecule precursors to produce PbSe by thermolysis in tri-n-octylphosphine oxide was investigated. The optical and morphological properties of the PbSe particulates were analysed; strong quantum confinement effects were observed in the optical spectra of nanodispersed PbSe in organic solvents.

  measurements on the nickel and zinc systems as well show that the four- membered chelate ring gains electron density in disfavor of the five-membered chelate ring during the mixed ligand complex formation. The ligand exchange reaction between the nickel complexes can be followed by means of UV-Vis spectroscopy. All reactions obey formally a second order rate law. The crystal and molecular structure of

  摘要1,3-二硫代-2-硫酮-4,5-二硫代镍，铜和锌的双螯合物与丙酮中的这些金属的二乙基二硫代，-硫代硒代-和二硒代氨基甲酸酯反应形成混合配体络合物[M （dmit）（XYCNEt 2）]-（X = Y = S或Se; X = S，Y = Se）只能单独分离为适当阳离子的盐。该合成可以扩展到包含由（Bu4N）2 [Ni（dmit）-（i-mnt）]（i-mnt = 1,1-二氰基乙烯-2,2-二硫醇盐）证明的其他双配体的混合配体系统。对铜化合物的EPR测量以及对镍和锌系统的1H，13C和77Se NMR测量也表明，在混合配体络合物形成过程中，四元螯合环获得了电子密度，而不是五元螯合环。镍配合物之间的配体交换反应可以通过紫外-可见光谱法进行。所有反应都正式服从二阶速率定律。报道了Bu4N [Zn-（dmit）（Et2dtc）]的晶体和分子结构。该化合物在晶胞中具有四个分子的正交晶体空间群Pna21结晶。a
