The molecule possesses approximate C2 symmetry with the pseudo-twofold axis passing through the unique sulfur atom u4-S(2) and the midpoint of the other two u2-sulfur atoms S(1) and S(3). The unique u4-sulfur atom has a tetrahedral geometry and donates its six valence electrons to the four iron atoms. The average Fe-(μ4-S) distance of 2.247 A is slightly shorter than the average Fe-(μ2-S) distance of 2.265A.

Synthesis, Structure and Photoluminescence of(CH3-4, 4'-H2bipy)-(HgCl4)with CH3-4, 4'-H2bipy Generated in Situ

A novel viologen(4,4'bipyridinium)-based complex(CH3-4,4'-H2bipy)(HgCl4)(1),in which the CH3-4,4'-H2bipy(MQ2+)was generated in situ,has been synthesized via hydrothermal reaction and structurally characterized.Complex 1 crystallizes in the space group P21/c of monoclinic system with four formula units in a cell:a = 8.1848(6),b = 21.809(2),c = 9.0285(6)(A),β =.107.377(1)°,V= 1538.0(2)(A)3,C11H11Cl4HgN2,Mr = 513.61,Dc = 2.218 g/cm3,S = 1.009,μ(MoKα)= 10.685 mm-1,F(000)= 956,R = 0.0360 and wR = 0.0812.The crystal structure analysis reveals that the title complex features an isolated structure based on a CH3-4,4'-H2bipy moiety and a mercury atom terminally bound by four chlorine atoms.Photoluminescence investigation reveals a strong emission in blue region,which may originate from π→π* charge-transfer interaction of the CH3-4,4'-H2bipy moiety.

Synthesis and Crystal Structure of Ho_4S_3Si_2O_7

1 INTRODUCTION Halide fluxes are excellent media for growing single crystals of chalcogenides[1~5]. On our research in the Ln-Cu-Zn-Se system to find new phases and to search for potential infrared ceramic materials, two new compounds, KHo2CuSe4 and KEr2CuSe4, were synthesized from the reaction of the precursor with KCl flux[6]. In an attempt to synthesize the homologous sulfide by the same method using KBr as flux in a sealed evacuated quartz tube, single crystals of Ho4S3Si2O7 w…
