“…ions and chalcogenidoantimonate anions via TM-S or TM-Se bond, the weak interactions between lanthanide (Ln) ions and chalcogenidoantimonate anions make the synthesis of ternary Ln-chalcogenidoantimonates a challenging task. However, our work has demonstrated that the chalcogenidoantimonate anions [SbS 4 ] 3-and [SbSe 4 ] 3-can coordinate to Ln(III) centers using coordinative amines as co-ligands, and a number of Ln-chalcogenidoantimonates have been solvothermally prepared in en, dien, and trien solvents [39][40][41][42][43][44].

New lanthanide(III) compounds [[Ln(tepa)(Cl)]-[Ln(tepa)(OH)] 2 (SbSe 4 ) 2 ] n (Ln=Sm, Eu), [H 2 tepa][[Ln(tepa)-(SbSe 4 )] 2 (OH) 2 ] (Ln=Eu, Gd, Ho) (tepa=tetraethylenepen-tamine) were prepared by solvothermal methods. Acting as a bidentate l-1j:2j-SbSe 4 bridging ligand, the [SbSe 4 ] 3-unit interconnects [[Ln(tepa)] 2 (OH) 2 ] 4? and [Ln(tepa)Cl] 2? (Ln=Sm, Eu) ions to form one-dimensional coordination polymers [[Ln(tepa)(Cl)][Ln(tepa)(OH)] 2 (SbSe 4 ) 2 ] n . The [SbSe 4 ] 3-unit acts as monodentate ligand to Ln(III) centers in [H 2 tepa][[Ln(tepa)(SbSe 4 )] 2 (OH) 2 ]. The different coordination modes of the [SbSe 4 ] 3-units in [[Ln(tepa)(Cl)][Ln-(tepa)(OH)] 2 (SbSe 4 ) 2 ] n and [H 2 tepa][[Ln(tepa)(SbSe 4 )] 2 -(OH) 2 ] are attributed to the size of Ln 3? ions. The bidentate l-1j:2j-SbSe 4 bridging ligand in [[Ln(tepa)(Cl)][Ln(tepa)-(OH)] 2 (SbSe 4 ) 2 ] n is observed in the lanthanide complexes of tetraselenidoantimonate ligands for the first time. All compounds exhibit steep band gaps between 2.04 and 2.31 eV at room temperature. Graphical abstract

Novel lanthanide selenidostannate polymers containing the soft‐base Sn2Se6 ligand, (H3O)n[La(tepa)(μ‐1κ2:2κ2‐Sn2Se6)]n (1), [{Nd(tepa)(μ‐OH)}2(μ‐1κ:2κ‐Sn2Se6)]n (2), and [{Gd(tepa)(μ‐OH)}2(μ‐1κ:2κ‐Sn2Se6)]n·nH2O (3) (tepa = tetraethylenepentamine) were prepared by treating lanthanide oxides with Sn and Se using pentadentate polyamine tepa as a second ligand under solvothermal conditions. In 1, the La3+ ion is coordinated by a tepa ligand to form an unsaturated [La(tepa)]3+ unit, and the [Sn2Se6]4– anion acts as a tetradentate bridging ligand with four terminal Se atoms to connect the [La(tepa)]3+ units into a coordination polymeric anion [La(tepa)(μ‐1κ2:2κ2‐Sn2Se6)–]n. The μ‐1κ2Se1,Se2:2κ2Se5,Se6 bridging mode in 1 is a new coordination mode for the Sn2Se6 unit to LnIII centers. In 2 and 3, the lanthanide ion is coordinated by a tepa ligand, and two [Ln(tepa)]3+ (Ln = Nd, Gd) ions are joined by two μ‐OH bridges to form dinuclear cations. Behaving as a bidentate μ‐Sn2Se6 ligand with the trans‐terminal Se atoms, the Sn2Se6 units connect the [{Ln(tepa)(μ‐OH)}2]4+ cations into neutral coordination polymers [{Ln(tepa)(μ‐OH)}2(μ‐Sn2Se6)]n. The coordination modes μ‐1κ2Se1,Se2:2κ2Se5,Se6 in 1 and μ‐1κSe1:2κSe5 in 2 and 3 are related to the metal size of the lanthanide(III) ions. In addition, as an ethylenepolyamine with higher denticity, the pentadentate tepa exhibits a significantly different influence on the structures of the solvothermally synthesized Ln selenidostannates compared to the bidentate ethylenediamine and tridentate diethylenetriamine. Compounds 1–3 are semiconductors with well‐defined band gaps of 1.95–2.34 eV.
