| Recently extensive interest has been focused upon the Main Group chalcogenidometalates due to their promising photoconductivity, photoluminescence , nonlinear optical properties, catalysis and ion exchange. 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. Organic hybrid thioantimonates [C3H7NH3]2Sb4S7 (1) and [C4H9NH3]2Sb4S7 (2) with layered structure was synthesized by solvothermal method in C3H7NH2 and C4H9NH2 solvents, respectively.2. The lanthanide-contained thioantimonates [Pr(en)3(H2O)(μ2-SbS4)] (3) and [Gd(en)4]SbS4·0.5en (4) were synthesized by solvothermal method in en solvent.3. The lanthanide-contained thiostannates [Ln2(en)6(μ2-OH)2][Sn2S6] (Ln = Dy (5), Er (6)) were synthesized in en, and [Dy2(en)6(μ2-OH)2][Sn2Se6] (7) was prepared by replacing S with Se. The ionic [Eu2(dien)4(μ-OH)2]Sn2Se6(7) was prepared by the reaction of SnCl4·5H2O, Se and Eu2O3 in dien. When Sn is used in stead of SnCl4·5H2O as strating material, compounds [Hdien][Ln(dien)2(μ-SnSe4)] (Ln = Sm (8), Eu (9)) are obtained under the same conditions.4. The synthesized chalcogenidometalates were characterized by elemental analysis, IR and X-ray crystallographic, and their thermal stability and optical properties were also investigated.
