| Recently extensive interest has been focused upon the Main Group chalcogenidometalates due to their promising photoconductivity, photoluminescence and nonlinear optical properties. The solvothermal reaction is becoming a versatile route to the chalcogenidometalates.The incorporation of transition metals or lanthanide metals with chalcogenidometalates will not only give rise to the change of structure, but also endue chalcogenidometalates with new properties. In this work, the major studies are as follows:1.The lanthanide thiostannates[Nd2(en)6(μ2-OH)2]Sn2S6(1) and[Gd2(en)6(μ2-OH)2] Sn2S6(2)(en= ethylenediamine) were first synthesized in en,a[Gd(dien)3]2[(Sn2S6)Cl2](3) was prepared by replacing en with dien. A selenidostannate[Gd2(en)6(μ2-OH)2] Sn2Se6(4) was obtained by using element Se instead of S.2.The selenidoantimonates[La(en)4(SbSe4)](5),[Nd(en)4(SbSe4)](6) and[Sm(en)4] SbSe4·0.5en(7) have been solvothermal synthesized. Compound[Fe(en)3(Hen)]SbSe4(8) was obtained using Fe3+ to replace Ln3+ ion.3.The chalcogenidometalates were characterized by elemental analysis, IR and X-ray crystallographic, and their thermal stability and optical properties were also investigated.
