The time of synthetic process was significantly reduced compared with previous synthetic routine. AU130（SPh-Br）50 was determined by UV-Vis absorption spectros- copy and matrix-assisted laser desorption ionization（MALDI） mass spectroscopy. Thermo-gravimetric analysis （TGA） and size-exclusion chromatogram（SEC） analyses confirmed the purity of AU130（SPh-Br）50. The yield of gold nanoc- lusters was 20%（based on HAuCl4）.展开更多
A new decanuclear silver(I) compound Ag10(8-S)(dtp)8 [dtp=S2P(OEt)2] was isolated from a reaction mixture containing W2S4(dtp)2 and AgNO3, and its solid-state molecular structure was determinated by X-ray crystallogra...A new decanuclear silver(I) compound Ag10(8-S)(dtp)8 [dtp=S2P(OEt)2] was isolated from a reaction mixture containing W2S4(dtp)2 and AgNO3, and its solid-state molecular structure was determinated by X-ray crystallography. The crystallographic study revealed that the compound contains a distorted mono-capped quasi-prism [Ag10] with an octat-bridging S atom at the center of the prism. The compound (C32H80Ag10O16P8S17, Mr=2592.46) crystallizes in the monoclinic P21/n space group, with a=1.5111(5) nm, b=2.3656(8) nm, c=2.284(1) nm, =96.88(3), V=8.107(5) nm3, Z=4 and Dc=2.12 g·cm-3. The solution using direct method and full-matrix least-squares refinement led to R=0.066, Rw=0.078 for 3928 reflections with I>3(I).展开更多
