A new tri-nuclear mixed metal thiolate complex [Ag(PPh3)2]2[Ni(edtO2)2] 1 has been synthesized and structurally characterized by single-crystal diffraction.The molecule has a crystallographic inversion centre occupied in the central Ni(II) atom and the two silver(I) atoms are related by the inversion centre.The unique structural feature is that one of thiolates of each edt ligand has been oxidized to sulfinate from the precursor [Ni(edt)2]2-to the neutral linear trinuclear complex.The crystal structure belongs to the monoclinic system,space group P21/n with a = 13.581(11),b = 12.239(9),c = 22.316(17) ,β = 103.08(2)o,V = 3613(5) 3,Z = 2,Mr = 1571.87,Dc = 1.445 g/cm3,μ = 1.046 mm-1,F(000) = 1604,T = 293(2) K,the final R = 0.0652 and wR = 0.1499 for 6776 observed reflections with I > 2σ(I). 相似文献
