The new binuclear tungsten compound (Et4N)2W2S4(tdt)2 (H2tdt=H2S2C6H3CH3) (I) with Mr=1067. 97 has been prepared and characterized by IR andX-ray single crystal analysis. 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.

Transition metal cyanides have been studied for a long time as such compounds process various interesting physical properties and can be used in many fields, such as catalyst, molecular-based magnets and zeolitic property. The cyanide ligand is of a versatile ligand which can assemble new complexes that may exhibit intriguing architectures and new topologies, many researches were focus on the copper cyanide system from viewpoint of structural engineering because of their diversity geometric constraints. On the other hand, helical structures have received especially much attention in the past few decades not only because helicity is essentially for life activity, but also due to their potential applications in asymmetric catalysis and nonlinear optical materials. Consequently, tremendous single or double helical chains have been generated, most helical polymers have been obtained by using helical *** this article we report the synthesis, crystal structure of one cyanide-bridged coordination polymer,[Cu2Fe(CN)4(1,10-phen)3]n·2nH2O (1). To our knowledge, compound 1 is the first example of a one-dimensional helical chain structure including different metal atoms which all have different coordination modes.

Laguerre polynomial’s photon-added squeezing vacuum state is constructed by operation of Laguerre polynomial’s photon-added operator on squeezing vacuum state. By making use of the technique of integration within an ordered product of operators, we derive the normalization coefficient and the calculation expression of ■. Its statistical properties, such as squeezing, the anti-bunching effect, the sub-Poissonian distribution property, the negativity of Wigner function, etc., are investigated. The influences of the squeezing parameter on quantum properties are discussed. Numerical results show that,firstly, the squeezing effect of the 1-order Laguerre polynomial’s photon-added operator exciting squeezing vacuum state is strengthened, but its anti-bunching effect and sub-Poissonian statistical property are weakened with increasing squeezing parameter; secondly, its squeezing effect is similar to that of squeezing vacuum state, but its anti-bunching effect and subPoissonian distribution property are stronger than that of squeezing vacuum state. These results show that the operation of Laguerre polynomial’s photon-added operator on squeezing vacuum state can enhance its non-classical properties.
