摘要
The synthesis,structure and luminescent property of a tetranuclear gold(Ⅰ)complex with doubly bridging diethyldithiocarbamate(Et2dtc)and 1,1-bis(diphenylphosphino)ethene((Ph2P)2C=CH2)are described.The complex crystallizes in monoclinic space group C2/c with a=26.785(7),b=25.654(6),c=12.277(3)A,β=106.879(5)°,V=8073(4)A^3,Z=8,C31H32Au2F6NO3P2S2Sb,Mr=1222.32,Dc=2.011 g/cm^3,F(000)=4592,Rint=0.0529,T=293(2)K,μ=8.157 mm^(-1),the final R=0.0464 and wR=0.1444 for 5804 observed reflections with I>2σ(Ⅰ).The intramolecular and intermolecular Au¨Au distances are 2.8670(9)and 3.2367(9)A,respectively.Weak emission appears at 517 nm at room temperature in the solid state.
