A new hexanuclear silver(I) compound containing thiosemicarbazones with groups of 1-naphthalene was synthesized and structurally characterized by single-crystal X-ray diffraction,elemental analysis and fluorescence spectrum.The title compound crystallizes in monoclinic,space group P2 1 /c with a=16.101(4),b=24.855(7),c=14.492(4),β=109.730(5)°,V=5459(3)3,C 90 H 102 Ag 6 N 24 O 6 S 6,M r=2455.54,D c=1.494 g/cm 3,μ(MoKα)=1.228 mm-1,F(000)=2472,Z=2,the final R=0.0761 and wR=0.1507 for 5258 observed reflections (I > 2σ(I)).In the structure,the S atom of ligand L serves as a triply bridged chelator to connect the six silver atoms into a Ag 6 L 6 cluster.Luminescence investigation reveals that the compound exhibits two ligand-independent cluster-centered electron transfer bands and one ligand-dependent charge transfer band.

一条大河是有灵魂的。    有很多次,我站在新安江边,端详着眼前的流水,安安静静地聆听并倾诉。它的声音从来就不是简单枯燥的,相反,她复杂、雄浑,同时又纤细入微,像音乐一样隽永深邃。我更愿意把这样的河流当作一部伟大的交响曲,而这样的交响曲,与时间长河一样,是拥有生命的。在皖南,新安江无与伦比。无与伦比是指她对于这块土地的影响力:她可以说是一条女性的河,也可以说是一条男性的河。说她是女性,是指她养育了

自1886年分离出元素氟以来,科学家们特别关心对抗其毒性作用的方法。因氟对钙强烈亲和;而且,鉴于急性氟中毒时血清钙的浓度低,推想钙是最合逻辑的氟的解毒剂。确实,在对动物
