摘　　要：Three two-dimensional(2-D) heterometallic chalcogenides [TM(tren)][InSbSe_3S](TM = Fe(1), Co(2), Mn(3); tren = tris(2-aminoethyl)-amine) have been solvothermally synthesized in this paper. Single-crystal X-ray analysis indicates that they are isostructural to each other except the different transition metal ions. These compounds contain an unsaturated complex cation [TM(tren)]^(2+), which can be further coordinated by the 2-D [InSbSSe_3]_n^(2n-) anion, resulting in a new neutral organic-decorated heterometallic chalcogenide. These compounds crystallize in monoclinic space group P21/c, with a = 11.768(12), b = 13.884(14), c = 11.095(11) ?, Z = 4, D_c =2.910 Mg·m^(-3), F(000) = 1304, M_r = 707.60 for 1; a = 11.843(9), b = 14.064(10), c = 10.979(8) ?, Z= 4, Dc = 2.875 Mg·m^(-3), F(000) = 1308, M_r = 710.68 for 2; a = 11.969(10), b = 14.191(11), c =11.112(9) ?, Z = 4, D_c = 2.779 Mg·m^(-3), F(000) = 1300, Mr = 706.69 for 3. The maximum and minimum peaks of compounds 1～3 are 6.996 and –2.880 e·?^(-3), 2.242 and –3.066 e·?^(-3), 3.655 and –3.569 e·?^(-3), respectively. These compounds were structurally characterized by powder X-ray diffraction measurement, thermal analysis, infrared spectroscopy and UV-Vis diffuse reflectance spectroscopy. A solid-state UV/Vis reflectance spectroscopy measurement on 1, 2 and 3 confirmed that these compounds are semiconductor materials.
