A new inorganic-organic hybrid lanthannm thioantimonate(V) with bidentate and tetradentate mixed amino ligands, namely La(teta)(en)(μ-η1,η2-SbS4) (1, teta = triethylenetetramine, en = ethylenediamine), ha...A new inorganic-organic hybrid lanthannm thioantimonate(V) with bidentate and tetradentate mixed amino ligands, namely La(teta)(en)(μ-η1,η2-SbS4) (1, teta = triethylenetetramine, en = ethylenediamine), has been solvothermally synthesized and structurally, thermally and optically characterized. In 1, the en ligand is in situ produced by re-aggregation of teta which plays multiple roles in the reaction as ligand, reactive solvent and precursor. Single-crystal X-ray analysis reveals that 1 belongs to the orthorhombic space group P212121. Its structure features a one-dimensional organic-inorganic hybrid chain of [La(teta)(en)(μ-η1,η2-SbS4)],, constructed by alternating arrangement of μ-η1,η2-sbvs4 tetrahedron and La(teta)(en) complex.

Single-crystal X-ray diffraction studies revealed that the title compound crystallizes in the monoclinic space group P2_1/c with a = 12.2458(7),b = 13.8588(7),c = 7.2292(4) ?,β = 99.460(6)°,V = 1210.20(12) ?~3,Z = 4,Dc = 2.108 g·cm^(-3),F(000) = 748,μ = 3.584 mm^(-1),R = 0.0348 and wR = 0.0823(I 〉 2σ(I)). The structure features a neutral two-dimensional(2D) network constructed by the unsaturated [Mn(1,2-DACH)] complexes interconnecting [SnS_3]_n^(2n-) chains via sharing S. Thermal stability and optical property of compound 1 were characterized.展开更多
