Compound (I) has been synthesized by two routes, ofwhich one was from the reaction of (NH4)WS4 with H2tdt, and the other is from lig-and substitution reaction of W2S4 (dip)2 by H2tdt. The compound contains a typical[W2S4j2+ moiety with a W-W bond of 2. 862(2) A. Its crystallographic data are: or-thorhombic, space group Pbca, a=23. 995 (9), b=31. 496 (7), c=10. 537 (5) A, V=7950(8) A3, Z=8, Dc= 1. 78 g·cm-3, p(MoKa)= 63. 37 cm-1 and R=0. 062 for1926 reflections with I≥3d(I). Synthesis, structure and reaction of the compound arediscussed in this paper.展开更多
